    Experiences from Using Open-Ended and Life-Resembling Problems in a Master Course2015Ingår i: Proceedings of the 11th International CDIO Conference, June 8-11 2015, Chengdu, China, Conceive Design Implement Operate, CDIO , 2015Konferensbidrag (Refereegranskat)
    Abstract [en]

    Finding the optimum balance between theory and practice is one of the major challenges in higher education. A student-centered approach to learning is argued for by several educational researchers and practitioners, and deep learning could be accomplished by activating the students during the education. This paper reports on experiences learned from a course in Maintenance Data Management, which is thought on the first year of a master’s program in Industrial Asset Management, and in specific on how knowledge and skills in computerized maintenance management systems were trained. The course consisted of a series of lectures, laboratory sessions, exercises and seminars. In addition, two study visits and one guest lecture were arranged. In this paper one of the activities is described in more depth. The activity is an exercise in IT system selection, where the students are asked to define functional and non-functional criteria for the evaluation of systems alternatives, to find suitable candidates for evaluation and finally conduct an evaluation and discuss the results. This exercise exemplifies ways to create more open-ended and real-life resembling problems that activates the student in the learning situation, and that simultaneously gives the students possibilities for advanced reasoning and reflection. The detailed learning outcomes of the exercise are described using the CDIO syllabus, and benefits as well as success criteria are highlighted in the conclusion.

    Formative and Summative Assessment: Contradictories or Joint Opportunities?2014Ingår i: Proceeding of the 10th international CDIO Conference: Sharing Successful Engineering Education Experiences, CDIO , 2014Konferensbidrag (Refereegranskat)
    Abstract [en]

    Formative assessment is used for monitoring student learning in order to provide the student with relevant feedback, while summative assessment is used to evaluate student learning outcomes. Traditionally, these two concepts are seen as counterparts or contradictories, and this might result in a belief that one is to be preferred in favour for the other. In fact, they both are important measures in creating an efficient learning environment, and in reality they are often combined. This contribution discusses the benefits of both concepts and in particular how one and same assignment could be utilised both for summative and formative purposes. The discussion is exemplified using experience from a first year course in project management and academic writing entitled “Technical projects and report writing”. In the course, summative as well as formative assessment methods are utilised. The interconnection between assessment methods and the integration of both summative and formative aspects in some of the assignments is highlighted. We will also address how the setup is communicated to the students and their feedback and reflections on the course and their learning outcomes.

    Hur skall utbildningen vara utformad? En studie i olika aktörers uppfattning om utbildningsutformning2015Konferensbidrag (Övrig (populärvetenskap, debatt, mm))
    Abstract [sv]

    Den traditionella utformningen av högskoleutbildning är den campusbaserade, teoretiska och lärarcentrerade kursen med föreläsningar och skriftlig tentamen. Trenden kan ses som den totala motsatsen till detta: I dag förespråkas distansbaserade utbildningar med flippade klassrum, och där studenten förväntas bara aktiv i lärprocessen och ta ansvar för sitt eget lärande. Men vad är det bästa alternativet?  Frågan beror naturligtvis på faktorer såsom ämne, studentgrupp, lärarkår och resurser som finns tillhands. Men genom att tydliggöra de konstraster som finns kan lärare och utbildningsadministratörer skapa en större medvetenhet kring utbildningsutformning och de för- och nackdelar olika tillvägagångssätt har. Om man dessutom frågar andra aktörer kopplade till utbildningen – studenter, presumtiva studenter (t.ex. gymnasieelever), alumni och näringslivsrepresentanter – klan man bättre förstå de förväntningar och behov man har på en viss utbildning. Detta gjordes för högskoleingenjörsutbildningen i Skog och träteknik i en studie under våren 2015.

    Ett underlag som täckte tio aspekter på utbildningsutformning togs fram som skulle fungera både för fokusgruppsdiskussioner och för enkäter. De tio aspekterna var utbildningens längd, distributionsform, utbildningstakt, andelen obligatoriska kurser, förhållandet teori och praktik samt universitet och näringsliv, globalt eller nationellt perspektiv, lärandesituation, arbetsform samt kunskapsutfall. Representanter för olika aktörer fick sedan svara på frågor kring dessa; presumtiva studenter, studenter samt alumner i enkätform, medan näringsliv och lärarkollegiet (inklusive administratörer) gjorde detta i fokusgruppsform. Speciellt diskussionen med näringslivsrepresentanter visade på att man kan ha mycket olika sätt att se på utbildningsutformning, och diskussionen som fördes i båda fokusgrupperna gav en djupare förståelse för den aktuella utbildningen, vilka möjligheter den har, vilka områden som kan förbättras, och hur utbildningen bör utvecklas.

    Detta rundabordssamtal tar avstamp i studien och de resultat och erfarenheter som erhållits. Därefter kommer åhörargruppen att få fylla i samma frågemall som användes i studien och en diskussion kring utbildningsutformning hålls med grund i de svar som åhörarna noterat.

    IT governance from the operational perspective: a study of IT governance strategies applied within maintenance management2018Ingår i: International Journal of Services Technology and Management, ISSN 1460-6720, E-ISSN 1741-525X, Vol. 24, nr 1-3, s. 263-288Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This paper investigates the existence and effects of different ITgovernance strategies on the operative level of manufacturing industries. Thestudy is based on a mixed research method including statistical analysisof questionnaire data and a qualitative analysis of interview material. Theoperational business unit that is being studied is maintenance and itsmanagement. Several types of IT governance strategies existed within thisbusiness unit according to the study, and the decentralised was the mostcommon. The different strategies had both a positive and negative impact onthe business unit, but the federal IT governance strategy seems to overcomesome of the problems in the others. The results indicate that there might beother characteristics worth testing than the ones used in this study, for instancethe size of the business unit.

    IT Practices within Maintenance from a Systems Perspective: Study of IT Utilisation within Firms in Sweden2013Ingår i: Journal of Manufacturing Technology Management, ISSN 1741-038X, E-ISSN 1758-7786, Vol. 24, nr 5, s. 768-791Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Purpose – The aim with this paper is to describe current IT practices within maintenance in Swedish industry, and to outline the future possible developments. Design/methodology/approach – The study is performed as a web-based questionnaire survey consisting of 71 participants. A systems perspective is applied for capturing the most relevant aspects of IT utilisation. Findings – The IT practices are characterised by high use of business-specific IT solutions, low use of company-wide IT solutions, low IT intensity and the client-server architecture is dominating. The purchase decision and ownership of IT is to high extent tied to the maintenance function. Moreover, IT systems are apprehended as beneficial and connected to real needs. The findings imply a decentralised IT governance form and a mainly vertical (functional) IT support. Research limitations/implications – The socio-technical approach suggested in this paper helps us to identify which areas to study, and also shows the tight interrelationship between different factors, layers and systems. Practical implications – The study results could be used for benchmarking purposes or to highlight state-of-the-art of IT utilisation in maintenance, and thereby set the topic on the corporate agenda. Originality/value – Studies describing IT utilisation within maintenance in the form of case studies and surveys exist, but they mainly focus on one aspect. This study approached the problem from a socio-technical perspective, covering several aspects connected to IT utilisation.

    Knowledge asset management in the maintenance context2013Ingår i: Congress Proceedings of COMADEM 2013, International Congress of Condition Monitoring and Diagnostics Engineering Management, Finland: KP media Oy , 2013, s. 9-16Konferensbidrag (Refereegranskat)
    Abstract [en]

    Knowledge could be viewed from two perspectives; the product perspective and the process perspective. Knowledge as a product will be represented in form of e.g. files, records and reports. Knowledge as a process emphasizes the creation of knowledge, which is supported by e.g. communication and collaboration. Both views are important for any business. The concept of knowledge asset management is a fusion of both perspectives. Knowledge asset management involves the identification and analysis of available, as well as required, knowledge assets and knowledge asset related processes. It also comprises the planning and control of the assets and the processes for achieving business goals.

     

    In this paper, we will discuss the maintenance process from the perspective of knowledge asset management. The important knowledge assets and processes are identified. Different  solutions for enabling effective knowledge management are thereafter discussed, with focus on available information and communication technology (ICT) for knowledge management and the current trends and developments in the ICT area, for instance in form of social networking and web 2.0.

    Project Management and Communication Skill's Development: Students' Perception on Their Learning2015Ingår i: Proceedings of the 11th International CDIO Conference, Chengdu, China, June 8-11 2015, Conceive Design Implement Operate, CDIO , 2015Konferensbidrag (Refereegranskat)
    Abstract [en]

    When a course has ended, the grades have been distributed, and the course evaluation is finished, one could still ask oneself if the course really gave something for the individual student. The final grade is a result of the assessment of the students’ skills in relation to stated learning outcomes according to the syllabus. But what if the students enter the course with different skills’ levels? If a specific student already possesses a certain amount of competence within an area, can he or she still learn something in a basic level course?

    In this paper we investigate the outcomes of a project management course in terms of syllabus fulfilment with regard to the students’ perception of increased learning. The course comprise theoretical as well as practical training in writing, study design and project management. The student group is heterogeneous and consists of national programme students as well as international exchange students representing a wide range of subjects, nations and previous study experiences. Therefore, even if the course formally is a first-year course, the real skills’ possession of the participating students varies a lot. This makes this course challenging to teach, and raises several questions: Do all students develop their individual skills during the course, disregarded of the skills level which they entered the course with? Are we focusing on the right set of skills, or are some skills more important to develop than other skills? How should we improve the design of the course to enable each individual student to develop their skills? The paper focuses on the first and second question, because understanding the problem is the first step in any improvement activities. This understanding could thereafter be used for improving the course syllabus in terms of contents, learning outcomes and activities.

    After a general discussion regarding personal and interpersonal skills’ development in higher education, findings from the course entitled Technical projects and report writing are presented. The course design and student characteristics are described and thereafter the work with assessment of skills’ development is described. We asked the students to state their skills level within x predefined areas connected to the course contents. In the end of the course, the students were asked to once again state their skills’ level. Results from the skills’ evaluation are presented and discussed, and conclusions regarding the possibilities to further improve the course design are drawn. The positive and negative aspects of homogenous student groups in project courses are also discussed.

    What Should We Teach?: A Study of Stakeholders’ Preceptions on Curriculum Content2016Ingår i: The 12th International CDIO Conference: Proceedings – Full papers / [ed] Jerker Björkqvist, Kristina Edström, Ronald J. Hugo, Juha Kontio, Janne Roslöf, Rick Sellens & Seppo Virtanen (eds.), Turku: Turku University of Applied Sciences , 2016, s. 266-278Konferensbidrag (Refereegranskat)
    Abstract [en]

    The Bachelor of Engineering is a complex form of education; it has to meet the requirements of higher education in terms of academic stringency and scientific approaches, and at the same time fulfil the requirements of the companies and other takers on employability and professionalism. The aim of the CDIO initiative is to help educational institutions to fulfil the latter without losing the academic basis. Several studies have been made asking different actors to give their view on education and needed competencies, but these are often delimited to one or a couple of actors. One possible reason is the complexity of conducting such studies. This paper reports on a survey including program students, alumni and industry representatives and covers their perceptions of what is important to include in a Bachelor of Engineering program, and what is not. The methodological issues and choices as well as the main results are accounted for. The program in focus is a three-year Bachelor of Engineering in Forest and Wood Engineering taught at Linnaeus University, and the questions regarding content were based on the CDIO syllabus.

     

    Results show that there are some contents all three groups of actors regard as important; all found knowledge in forestry, material sciences and technology related to wood industry as important. Also, analytic and communication skills, and the ability to work in groups were seen as important. Understanding social and environmental conditions and enterprise and business terms was also necessary. Least important was the ability to communicate in foreign languages and knowledge regarding construction technology and deepened knowledge of forestry.

    The Thinking Industry: An approach for Gaining Highest Advantage of Digitalisation within Maintenance2017Ingår i: Journal of Maintenance Engineering, Vol. 2, s. 147-158Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Digitizing is on top of many agendas as one solution to industrial problems and in realizing Industry 4.0. By digitizing production one can achieve process efficiency and flexibility as well as resource effectiveness throughout the whole life cycle. The smart factory of tomorrow is characterized by adaptive and self-regulating cyber-physical and real-time connected systems. However, without a clear purpose, and without taking advantage of all the intellectual as well as material resources in the industry, it will risk becoming a fad like many others. Smart IT solutions must be combined with smart people and a smart approach to digitizing. The focus should be on optimizing the maintenance throughout the asset lifetime and  on matching digitalization efforts with suitable maintenance strategies based on the needs of the operations. The basic idea behind the concept of “The thinking industry” is to see upon the future with a system’s perspective based on the motto “think hard, think right, think system(atically)”. This paper describes the concept of “The thinking industry” and how it supports the digitizing of maintenance. Moreover, a general work process is proposed and exemplified.

    The Impact of Maintenance 4.0 and Big Data Analytics within Strategic Asset Management2017Ingår i: MPMM 2016, Maintenance, Performance, Measurement & Management: conference proceedings / [ed] Diego Galar, Dammika Seneviratne, Luleå: Luleå tekniska universitet , 2017, s. 96-103Konferensbidrag (Refereegranskat)
    Abstract [en]

    The latest industrial revolution is manifested by smart and networking equipment. Realizing the full value of these machineries, and other business assets, has become increasingly important. Strategic asset management faces managerial, technical as well as methodological challenges, of which some could be reduced or overcome by applying technological solutions such as Internet of things, cloud computing, cyber-physical systems and big data analytics. This paper outlines the impact of the emerging technologies in the area of strategic management with special emphasis on the analytics as service provider for the maintenance functions.

    Maintenance 4.0 in Railway Transportation Industry2016Ingår i: Proceedings of the 10th World Congress on Engineering Asset Management (WCEAM 2015) / [ed] Koskinen, KT; Kortelainen, H; Aaltonen, J; Uusitalo, T; Komonen, K; Mathew, J; Laitinen, J, Springer, 2016, s. 317-331Konferensbidrag (Refereegranskat)
    Abstract [en]

    Transportation systems are complex with respect to technology and operations with involvement in a wide range of human actors, organisations and technical solutions. For the operations and control of such complex environments, a viable solution is to apply intelligent computerised systems, such as computerised traffic control systems for coordinating airline transportation, or advanced monitoring and diagnostic systems in vehicles. Moreover, transportation assets cannot compromise the safety of the passengers by applying operation and maintenance activities.  Indeed safety becomes a more difficult goal to achieve using traditional maintenance strategies and computerised solutions come into the picture as the only option to deal with complex systems interacting among them trying to balance the growth in technical complexity together with stable and acceptable dependability indexes. Industry 4.0 is a term that describes the fourth generation of industrial activity which is enabled by smart systems and Internet-based solutions. Two of the characteristic features of Industry 4.0 are computerization by utilising cyber-physical systems and intelligent factories that are based on the concept of "internet of things". Maintenance is one of the application areas, referred to as maintenance 4.0, in form of self-learning and smart systems that predicts failure, makes diagnosis and triggers maintenance by making use of “internet of things”. This paper discusses the possibilities that lie within applying the maintenance 4.0 concept in the railway transportation industry and the positive effects on technology, organisation and operations from a systems perspective.

    Analyzing the meaning of interdisciplinary in the CDIO context2016Ingår i: Proceedings of the 12th International CDIO Conference, Turku University of Applied Sciences,Turku, Finland, June 12-16, 2016. / [ed] Jerker Björkqvist, Kristina Edström, Ronald J. Hugo, Juha Kontio, Janne Roslöf, Rick Sellens, Seppo Virtanen, Turku: Turku University of Applied Sciences , 2016, s. 962-973Konferensbidrag (Refereegranskat)
    Abstract [en]

    Companies search for potential recruits with interdisciplinary skills. Consequently, to meet this requirement, universities and teaching institutions develop and offer interdisciplinary courses and programs. However, the meaning of interdisciplinarity varies between different actors. In order to be able to compare, monitor and evaluate concepts, it is important to ensure that the concept have the same meaning and content for all actors. Hence, the purpose of this paper is to describe the term interdisciplinarity and its application in higher education with specific focus on CDIO related literature. Moreover, dimensions of interdisciplinarity will be illustrated in an ongoing master program.

    This paper consists of two parts. The first part is a theoretical study conducted in order to describe the concept and illustrate the width of applications of interdisciplinarity in the CDIO context. For this purpose, the content of the CDIO knowledge library was surveyed using the following key words: inter*, cross*, trans*, interdisciplinary*, crossdisciplinary*, and transdisciplinary*. The second part is empirical in nature and describes an on-going interdisciplinary master program named “Innovation through Business, Engineering and Design” offered at the Linnaeus University, Sweden, as well as its dimensions of interdisciplinary.

    The CDIO approach advocates integrated learning experiences and the use of disciplinary competencies for solving interdisciplinary problems. This is reflected in the body of knowledge represented by the CDIO library: most of the articles reviewed in this study are describing interdisciplinary or transdisciplinary activities. The interaction could be between subjects, skills and courses within the discipline, i.e. in a cross-disciplinary or multidisciplinary mode, or between students representing different disciplines in multidisciplinary, interdisciplinary or transdisciplinary mode. Faculty staff acts as designers and enablers of these activities, both in terms of curriculum development on strategic level and activity creation and activity execution on the operational level. The practical example given in the paper illustrates the importance of an effective administration for succeeding with interdisciplinary activities.

    Student perspectives on interdisciplinarity: findings from an interdisciplinary two-year master program2018Ingår i: Proceedings of the 14th International CDIO Conference: Kanazawa in Japan, June 28-July 02, 2018 / [ed] Casey Bean, Jens Bennedsen, Kristina Edström, Ron Hugo, Janne Röslof, Robert Songer & Tomohito Yamamoto (eds.), Kanazawa, Japan, 2018Konferensbidrag (Refereegranskat)
    Abstract [en]

    The business environment has changed significantly during the last decade; globalization and short innovation cycles have become every-day business. These changes have formed new conditions for the companies and organizations: few of the problems encountered can be answered within a single discipline. Hence in order to address contemporary problems, companies and organizations need to have labor and recruit students with interdisciplinary skills. Consequently higher education must correspond to the business world’s changing needs by providing interdisciplinary programs. The purpose of possessing interdisciplinary knowledge and skills is to have the ability to understand the origin and nature of related disciplines as well as to relate these to its own discipline. Interdisciplinary skills could be viewed as an intangible type of knowledge that needs to be taught by and learned at the university. By possessing interdisciplinary skills, the labor and students will have a holistic view as compared the view related to one single discipline. The challenge, for the universities, lies in teaching and to ensure that the students possess interdisciplinary knowledge and skills. This paper focuses on students’ perceptions of interdisciplinarity and where it is taught and learned in a two-year master program. The purpose is to identify and analyze students’ perceptions of learning interdisciplinarity in a two-year master program. This paper is based on focus groups and personal interviews with students enrolled in the interdisciplinary two-year master program named “Innovation through business, engineering and design” hosted by the Linnaeus University. The two-year master program aims to enroll about 30 students each year from the disciplinary areas of Business, Engineering and Design. The paper concludes that the students perceive interdisciplinary as challenging and that interdisciplinarity require disciplinary skills and competences as well as personal and interpersonal capabilities. The students’ perceptions of interdisciplinary learning appear to be in line with the notion that learning is primarily to see things from different perspectives. Interdisciplinarity appears first and foremost in team work and communication. Tendencies towards a modification of the disciplines were noticed by the authors, which might lead to new disciplines evolving, such as “innovation design” or “innovation engineering”.

    Maintenance Practices in Small and Medium Sized Enterprises2013Ingår i: Congress Proceedings of COMADEM 2013, International Congress of Condition Monitoring and Diagnostics Engineering Management, Finland: KP media Oy , 2013, s. 669-675Konferensbidrag (Refereegranskat)
    Abstract [en]

    Small and medium sized enterprises (SME) constitute approximately 70% of the gross national product and account for 80% of the global economic growth. SMEs could thus be seen as a driving force of economic growth. Maintenance management plays a critical role in enterprises’ strategic objectives and achieving the competitive advantages desired, and affects the enterprises’ internal effectiveness. To apply an efficient maintenance strategy is therefore of importance for SMEs as well as lager enterprises. As a prerequisite for improvement, one must understand the current situation. But few studies of the maintenance practices in SMEs have been carried out in the past. This paper combines findings from two studies of Swedish industry, one covering SMEs as well as large industries, and one covering only SMEs, in order to depict the current maintenance practices in Swedish SMEs.

     

    Results show that SMEs put most time on execution of maintenance and less on planning and following up and that personnel and spare parts bear the largest costs. The most common trigger of maintenance actions is reported problems, followed by original equipment manufacturer recommendations and sudden failures. Condition monitoring data and statistical analysis are less common triggers though. Quite surprising, the practices in SMEs did not differ that much from the ones in larger enterprises. Sudden failures were less common as trigger for larger companies, and they utilise condition monitoring to a higher extent. Moreover, some more time is allocated for planning in larger companies compared with SMEs. The spare parts cost forms a smaller part in the total budget for larger enterprises. It is concluded that SMEs and large industries have more in common with respect to maintenance practices than they differ.

    Interdisciplinary, International and Industial Cooperation Efforts within the Mechanical Engineering Department2014Ingår i: Proceeding of the 10th international CDIO Conference: Sharing Successful Engineering Education Experiences, CDIO , 2014Konferensbidrag (Refereegranskat)
    Abstract [en]

    Cooperation is a multi-faceted concept in higher education. It could denote the cooperation between industry and academia, enabling students to train problem solving in a real life context. It could also describe the internationalization efforts found in teachers’ and students’ exchange programs. Moreover, cooperation exists between disciplines in order to enable a holistic perspective on course contents. This paper describes experiences of teaching some courses where all these aspects of cooperation are utilized for reaching the best possible conditions for teaching. The courses are within Machine Design, Product Development, Project Management, and Degree Project, and are all taught in English and contain projects in cooperation with industries. These courses are dealing with different approaches to the industrial projects to give the students an overall view and understanding of the real engineering work. The practical work is in form of student driven industrial projects, where students from the Mechanical Engineering Department at Linnaeus University collaborate with international students. The industrial related projects results in valuable real life experiences. The background of students from different countries and experiences of international teachers enriches the teaching process and students’ teamwork activities. Another result is the valuable culture exchange between the students and teachers which gives skills for future engineers to work in the European or global labor market. The implementation of the courses is described with focus on how cooperation between industry and academia, as well as between different competences at Linnaeus University and the University of Rousse, Bulgaria are utilized for creating optimal learning conditions.

    A framework for business model development for reaching service management 4.02016Ingår i: Journal of Maintenance Engineering, Vol. 1, s. 398-407Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The shifting demands on product development and production processes have led to the emergency of new business models, such as integrated product-service offerings. Research shows that the combined business models have a positive effect on the business and as a consequence the importance of aftersales services has increased. But many companies have not yet understood the business opportunities that could be achieved by providing aftersales services. The view of operations and maintenance services has to change; the focus should be on the values created and not in the offers in form of products or services. The approach presented in this paper is an attempt to support this mental shift. A framework for business model development is presented and its applicability in the practical work for reaching new business models is demonstrated by an example. The framework describes business model development in four levels. From maturity point of view, the four steps could be seen as the logical development of the business model from a narrow technical perspective to a holistic product-service perspective. The four levels could be connected to the four industrial revolutions according to the concept of Industry 4.0. Level four is therefore referred to as Service Management 4.0; a business model that supports Industry 4.0 and Maintenance 4.0. In particular, three key concepts reflect the concept of Service Management 4.0: performance-based contracts, partnering and the business ecology concept.

    Business Model Development towards Service Management 4.02016Ingår i: Product-Service Systems Across Life Cycle / [ed] Cavalieri, S; Ceretti, E; Tolio, T; Pezzotta, G, Elsevier, 2016, Vol. 47, s. 489-494Konferensbidrag (Refereegranskat)
    Abstract [en]

    There is an increasing interest to ensure operational and maintenance (O&M) operations from a strategic perspective, and there are opportunities for both producing companies and service providers to gain benefits. Research shows that the combined business models (products combined with services) have a positive effect on the business. Likewise, it is profitable to think strategically and in long term for enterprises offering maintenance services, especially using performance-based models. But for achieving these benefits the view of the business has to change. The focus should be on the values created and not in the offers in form of products or services. Moreover, the company needs to position itself as an actor not only in the value chain, but in a wider context referred to as the business ecosystem. Making such a shift of focus is hard though, and there is a need to understand both the current state of the business as well as the potential future directions. 

     

    The framework presented in this paper is an attempt to meet these needs. The framework describes business model development in four levels. From maturity point of view, the four steps could be seen as the logical development of the business model from a narrow technical perspective to a holistic product-service perspective. The four levels could also be connected to the industrial development where level four supports Industry 4.0. Level four is referred to as Service Management 4.0. In particular, four key concepts reflect the concept of Service Management 4.0: the mix of products and services in customer offers, performance-based contracts, partnering and the business ecology concept.

    Business Models for After Sales Services — Current State and Future Directions2016Ingår i: Proceedings of the 10th World Congress on Engineering Asset Management (WCEAM 2015) / [ed] Koskinen, KT; Kortelainen, H; Aaltonen, J; Uusitalo, T; Komonen, K; Mathew, J; Laitinen, J, Springer, 2016, 1, s. 333-346Konferensbidrag (Refereegranskat)
    Abstract [en]

    The core strategic decisions describing what, where, how and whom to make business with are defined in the business model. The business models adapted by industry have evolved as a consequence of changes in the business environment, the production processes as well as in technology, and the modern, innovative business models focus on long term relationships, performance-based and value-driven customer offers, and knowledge intensive processes. Other aspects are the increased complexity of the offer itself and a holistic perspective on the full value chain. This paper reviews the literature with respect to business models, business strategy and business innovation for postproduction activities, i.e. operations and maintenance (O&M) services. The purpose is to describe the current state within the area and based on this give directions for future research and development. Four main aspects are found as being important for the successful development of O&M service models: the mix of products and services in customer offers (bundling), relevant setup and metrics for performance-based business models and contracts, Information and Communications Technology (ICT) as an enabler and a prerequisite for business model development, and the need for a holistic view on the value chain by utilising the asset management concept.

    Modular-Based Framework of Key Performance Indicators Regulating Maintenance Contracts2019Ingår i: Asset Intelligence through Integration and Interoperability and Contemporary Vibration Engineering Technologies: Proceedings of the 12th World Congress on Engineering Asset Management and the 13th International Conference on Vibration Engineering and Technology of Machinery / [ed] Joseph Mathew C W Lim Lin Ma Don Sands Michael E. Cholette Pietro Borghesani, Springer, 2019, s. 301-310Kapitel i bok, del av antologi (Refereegranskat)
    Abstract [en]

    Key performance indicators (KPI) are necessary for regulating maintenance performance, setting goals as well as for follow up and improvement. Several standards and models for measuring maintenance performance exist today, but these are mainly developed for in-house maintenance. For outsourced maintenance, which is regulated in a service contract, other kinds of KPIs are needed. The procurement of maintenance and contract forms is also changing; an alternative to the traditional maintenance contract based on fixed price and predetermined activities are the performance-based contracts. Cooperation contracts based on mutual trust and fairness for all parties are also available. New KPI models for regulating maintenance service contracts are therefore needed. In this paper, a KPI framework for maintenance contracts based on the concept of modular maintenance offerings is proposed. Modular maintenance offerings is a way to classify maintenance services offerings with increasing integration of the offering, and increasing focus on utility for the customer and the business ecosystem. The KPI framework proposes indicators for regulating contracts on three levels (resource, performance and utility level) and includes six categories of indicators: economic, technical, organisational, quality, safety and health, and relationship between actors.

    School-wide approach for the degree project courses2013Ingår i: Proceedings of the 9th International CDIO Conference, Massachusetts Institute of Technology and Harvard UniversitySchool of Engineering and Applied Sciences, Cambridge, Massachusetts, June 9 – 13, 2013.: Engineering Leadership in Innovation and Design, 2013Konferensbidrag (Övrigt vetenskapligt)
    Abstract [en]

    The poster contains a practical example of how the CDIO concept can be used for developing common course contents with the aim to improve the students’ generic and professional competences. The overall purpose is to create a school-wide spirit of community for the students and introduce CDIO for faculty.

    OBJECTIVES

    1. Ideas for how to coordinate school-wide activities aiming at increasing students’ generic skills and professional identity

    2. Strategies for introducing the CDIO concept for the school faculty members

    DESCRIPTION

    For reaching high employability, students require knowledge and skills connected to the future working area, as well as generic skills and a professional attitude [1]. Ensuring these abilities is a major challenge of higher education today [2-4]. All these abilities are trained in the final independent work, where students, normally in collaboration with industry, acts as professionals while fulfilling the goals of academy. In the past, every subject had their own way of running the degree courses, but a need to coordinate the efforts for assuring the required outcome has gradually evolved. This emerging need was used as an opportunity to introduce CDIO thinking on school level, because most staff is involved in the degree project courses. Activities open for all students, such as joint introduction and lectures, workshops in literature search and a final dinner together with industry collaborators, are offered during the final semester, and general tools supporting the process have been developed, covering templates for report writing, a common web portal and a web based tool for registering of degree theses. The approach is extended with faculty pedagogic development activities, such as discussion meetings regarding generic skills training and the tutors’ role in the learning process.

    Framtagning av bedömningsmall av produktleverantörer i stålbyggnadsbranschen: Fallstudie på Llentab AB2017Självständigt arbete på grundnivå (yrkesexamen), 15 poäng / 22,5 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Inköp och leverantörsval påverkar företags konkurrenskraftighet. För att behålla sin position på marknaden och skapa långsiktiga relationer måste företag välja rätt partnerföretag. Företag kan uppnå sitt mål med leverantörsrelationer med hjälp av begränsat antal samarbetspartner, rätt bedömning och segmentering av leverantörer.

    Inköpsprocess och bedömningsmetod studerades på ett fallföretag för att erhålla information om ett nuvarande läge som sedan med hjälp av teori kunde operationaliseras och analyseras. Detta görs i huvudsak med hjälp av Multi-Criteria Decision Making, Kraljic matris och inköpspolicy.

    Resultatet presenterades med hjälp av sex leverantörer. För att leverantörerna ska vara godtagbar skall alla ‘obligatoriska’ krav uppfyllas i inköpspolicyn och erhålla ett önskat läge i Kraljic matris.

    Nyckelord: Kraljic matris, leverantörsbedömning, standardiserad bedömningsmall, inköpsprocess, Multi-Criteria Decision Making, Analytical Hierarchical Process, BFP-Bedömningsmall för produktleverantörer.

    Kapacitetsoptimering genom standardiserat arbetssätt2019Självständigt arbete på grundnivå (yrkesexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    För att möta en ökande efterfråga och samtidigt bibehålla konkurrenskraft krävs många gånger en optimering av produktionskapaciteten. Det påstås att det kan uppnås genom implementering eller utveckling av standardiserat arbetssätt. Studiens syfte är därför att undersöka hur standardiserat arbetssätt påverkar produktionskapaciteten i avsikt att generera lösningsförslag som optimerar produktionskapaciteten. Undersökningen utfördes som en fallstudie på en monteringslinje hos Getinge Disinfection AB i Växjö. Studiens genomförande följde DMAIC processen, vilket är hjärtat av Six Sigma, i avsikt att garantera att framtagna lösningar går att implementera på liknande processer. Studien resulterade i en reducering och balansering av cykeltider som genererade en approximerad kapacitetsökning på 184,3%. De förbättringsförslag som testades var framförallt förflyttning av delmonteringar till förmontage och förflyttning av arbetsmoment till andra stationer samt hur olika typer av slöseri kan elimineras.

    Challenges in teaching product development using industrial projects-experiences from Linnaeus university2013Ingår i: 7TH INTERNATIONAL TECHNOLOGY, EDUCATION AND DEVELOPMENT CONFERENCE (INTED2013) / [ed] Chova, LG Martinez, AL Torres, IC, The International Academy of Technology, Education and Development, 2013, s. 4659-4667Konferensbidrag (Refereegranskat)
    Abstract [en]

    In the presented paper the authors expose their experience with caring out a course "Systematic Approach" to the "Product Development", at Linnaeus University, Sweden. Product Development is a process based on a number of techniques and methods applied in correct order to achieve the best result in design and innovation tasks. For successful product development in a present competitive market interdisciplinary different types of skills are required. The mission of the course is to prepare future leaders in new products' engineering and management. Teaching such abstract subject, where at every step decision making in aesthetic, engineering and economic issues is required, is a real challenge for the course instructors. The fundament in this course is industrial projects, about real products. The participating students must understand the theory given in the lectures at the same time as they have to manage to apply it in development of different type of products. Students from different backgrounds like Mechanical Engineering and Business Engineering programs, and exchange students from eight different countries were participating in the course. They were divided in missed groups of four people in each group. Every three groups were competed each other through solving the same problem. The projects finished with concept designs, based on identified customer needs, concept generation, developed product architecture, and project management.

    Planning, accomplishing, and examining of an industrial project-based course within the field of product development2014Ingår i: INTED2014: 8TH INTERNATIONAL TECHNOLOGY, EDUCATION AND DEVELOPMENT CONFERENCE / [ed] Chova, LG Martinez, AL Torres, IC, The International Academy of Technology, Education and Development, 2014, s. 189-197Konferensbidrag (Refereegranskat)
    Abstract [en]

    Participating in product development course requires not only learning the theory delivered in the lectures but also learn how to combine the knowledge developed in previous courses with the systematic way of thinking in order to take right design decisions. This aim is achieved in a best way, if the educational process is accomplished in cooperation with the industry. Organization of a course based on industrial projects is not an easy task. The most difficult issues are to find suitable projects for the topic, adequate for the size of the course, and to fit to the background of the students. Before starting such course, it needs huge efforts to plan and prepare right proportions of theories, examples, seminars, and project group consultations. Although everything would be planned and scheduled in details, many problems may show up during running the course. The problems can be conflicts and miscommunications within the groups, and/or miscommunications between student groups and companies or teachers. The mixture of program-and international students with different cultural-and educational background does not always make the situation easier. The fair assessment for individual students needs different approaches from the teachers' side when the examinations of the projects are based on the reports prepared by groups. This paper is presenting experiences from teaching a project-based Product Development course with real projects from the industry. The course is given in English for program-and international students.

    Teaching design of mechanical transmissions in an international classroom - experiences and reflections2017Ingår i: INTED2017: 11TH INTERNATIONAL TECHNOLOGY, EDUCATION AND DEVELOPMENT CONFERENCE / [ed] Chova, LG Martinez, AL Torres, IC, IATED-INT ASSOC TECHNOLOGY EDUCATION & DEVELOPMENT , 2017, s. 6007-6016Konferensbidrag (Refereegranskat)
    Abstract [en]

    The topic of mechanical transmission design is one of the fundamental parts in the subject of machine design, and it is taught almost in all the mechanical engineering programs around the world. The fundamentals are the same but the teaching methods, literature and the instruction language are different from country to country, and from university to university. Although the bachelor program in mechanical engineering at Linnaeus University (LNU), Sweden is taught in Swedish, there are some courses given in English language both for the program-and international students. The international students are usually exchange-or free movers staying at LNU for one semester or for a whole academic year. The English courses are usually in the final year of the program, which means almost all international students have different background, skills and knowledge. The mix of program students and students from different countries in an international classroom is an excellent opportunity to gain international experiences but it is also a real challenge both for teachers and student groups. This paper is presenting many years experiences and result from teaching machine transmission design though project based learning for classes mixed of program-and international students at Linnaeus University in Sweden.

    Metod för identifiering av slöserier samt kostnadseffektiva förbättringsmöjligheter: en fallstudie2015Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Bakgrund: Att utveckla och förbättra organisationer genom effektivare användning av de resurser man har till förfogandet har blivit allt mer betydelsefullt under de senaste decennierna. Genom fokusering kring de aktiviteter som tillför värde hos kunden i slutprodukten kan företag reducera och eliminera oönskade slöserier inom tillverkningsprocessen. Ett verktyg som utvecklats och används för att eliminera dessa oönskade aktiviteter så som lagerhållning är Value stream mapping (VSM).

     

    Problemformulering: Hur kan man identifiera slöserier samt dess förbättringsmöjligheter för att möjliggöra en högre produktionskapacitet genom frigörandet av anläggningsyta?¨

     

    Syfte: Genom användandet av VSM som modell, identifiera slöserier och kostnadseffektiva förbättringsmöjligheter.

     

    Metod: Denna fallstudie har utförts på ett företag som arbetar inom metallindustrin. Större delen av datainsamlingen har tagits från företagets egna dokumenterande data samt intervjuer med anställda och observationer under de besök författarna genomförde.

     

    Slutsatser: Genom att använda VSM som en modell har författarna lyckats identifiera fallföretagets största faktorer till slöserier samt ge förslag och underlag till framtida förbättrings implementationer av förbättringsstrategier. Författarna har bevisat utifrån den teoretiska data studien är grundad på gentemot den empiriska att flertal förbättringsmöjligheter utöver den som företaget tänkt sig finns till deras förfogande vid eventuell framtida implementering.

    Att arbeta med förebyggande förändring på producerande företag2013Självständigt arbete på grundnivå (högskoleexamen), 15 poäng / 22,5 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    En förändring är ett tillstånd som vi upplever under hela vår livstid, både privat och i arbetslivet. Företag måste förändras för att kunna bevara sin konkurrens-kraft. Motstånd till förändring kan anses som det största enskilda hotet mot ett framgångsrikt införande av en strategi på ett företag. Ett sätt att hantera detta motstånd är att använda sig av den delaktiga förändringsmodellen samt stävja rädslor och osäkerhet.

     

    Syftet med detta examensarbete var att vi ville få en ökad förståelse för hur företag arbetar med produktionsförbättringar och om de känner av något motstånd vid dessa förändringar. De intervjuade företagen anger som sin absolut största förändring deras införande av ett eget produktionssystem med stort fokus på Kaizen – Ständiga förbättringar.

     

    Under arbetets gång stötte vi på en psykologisk och vetenskaplig teori om Förändringens fyra rum som anses vara ett kraftfullt hjälpmedel vid alla förändringar.

    Wind turbine blade modeling - setting out from experimental data2013Självständigt arbete på avancerad nivå (magisterexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [en]

    Complex systems can be divided into simpler substructures. Determining the properties of each subcomponent by experimental procedures is practical and can serve to verify or calibrate finite element models. In this work, an existing model of a wind turbine blade was improved by use of experimental data. Such a blade is a subpart of a complete wind turbine. For calibration purpose, several material tests were made in order to determine the stiffness and mass properties. Later on, vibration tests of the blades were conducted and compared with simulation results of the improved model. Geometry variability within sets of blades was also studied. The blade twist angles and the center of gravity positions were found to vary moderately, which accounts for differences in blades’ dynamic behavior. Correlations between experimental data and analytical model results were very high for the first eight modeshapes. That is, according to the Model Assurance Criterion the calibrated model achieves a high-quality representation of reality. However, torsional modes in the computer model occur at a higher frequency than the experimental ones. Substructuring of the turbine allows the blades to be modeled and validated independently of the other substructures and can later be incorporated into a complete model of the turbine.

    An initial investigation of the correlation between a number of drilling related quantities measured during down the hole drilling2017Ingår i: Proceedings of the 24th International Congress on Sound and Vibration, Curran Associates, Inc., 2017Konferensbidrag (Övrigt vetenskapligt)
    Abstract [en]

    Optimizing the performance for down the hole (DTH) drills is becoming increasingly important. This is due to that the industry is becoming highly competitive and therefore there is an ever-increasing demand for improving the efficiency of the drilling process. To do this, it is important to have a robust monitoring system in place that should be based on in-depth knowledge of the underlying physics of the drilling system and process. Such a system will assist drillers in improving the perfor-mance e.g. by providing recommendations concerning the settings of the drilling. To understand the performance of the system, it is very important to understand the information that can be extracted from different drilling related quantities. In this work, information obtained from the pressure signals from the feed/holdback line, impact pressure line and rotation line together with vibration signals measured with the aid of accelerometers mounted at specific locations on the drill rig are discussed. For instance, spectral properties of these quantities for good and bad drilling cases are investigated. The results indicate correlations, to some extent, between the spectral properties and the quality of the drilling.

    The drilling industry is steadily moving towards automation. To have a better control over the drilling operation and to optimize the drilling performance, it is necessary to have a good understanding of the physics involved in the process. A good simulation model of the drilling process/system would be of great value in assisting this and in enabling the development of strategies to optimize it. A representative simulation model can provide insights into various phenomena that appear during drilling for different drilling conditions. Such a model is also likely to be of assistance in preparing various measurements. Issues such as choosing the type of sensors, their positions and which quantities to measure are supported by a model. A well calibrated model in combination with information extracted from measured data are hence likely to assist in selecting control strategies for optimized drilling performance. In this paper we present a MATLAB based 1D simulation model of a Down The Hole (DTH) drill and compare it with an existing 1D model in terms of computational speed and accuracy. The emphasis is to make a 3D model of a DTH system that is computationally efficient and accurate.

    Förbättrad lagerhållning genom identifiering av kärnprocesser : En fallstudie av Nordic E- commerce Group 2014Självständigt arbete på grundnivå (kandidatexamen), 15 poäng / 22,5 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Syftet med detta arbete är att öka förståelsen för hur kärnprocesser kan förbättra lagerhållningen i ett företag. Genom att först kartlägga vilka företagets kärn- och stödprocesser är och sedan undersöka hur kärnprocesserna påverkar lagerhållningen kan syftet uppnås. Därmed besvaras problematiseringsfrågan som är följande;

    På vilka sätt kan lagerhållningen, genom identifiering av kärnprocesserna förbättras på ett företag med E-handel?

    Arbetet har genomförts på ett av koncernen Nordic E-Commerce Groups dotterbolag, Nordic Inc som är ett E-handelsföretag som säljer bläckpatroner och kontorsmaterial till både företag och privatpersoner.

    Inledningsvis genomfördes en kartläggning av Nordic Incs processer genom observationer och intervjuer med koncernens VD. När kartläggningen var sammanställd visade det sig att de kärnprocesser som fanns på Nordic Inc var Lager, Inköp och Kundservice. Dessa behandlades sedan mer ingående genom intervjuer med cheferna för varje kärnprocess för att se hur kärnprocesserna påverkar lagerhållningen.

    Det visade sig vara på sådant sätt att kundservice inte påverkar lagerhållningen på något sätt. Snarare tvärt om då kundservice blir lidande på grund utav den bristande lagerhållningen. Tillvägagångssätten på lagret påverkar lagerhållningen genom bristande artikelplacering, svårtillgänglighet, bristande kontroll över lagersaldo och artiklarnas skick. Vilket i sin tur påverkar kostnader för inventarier och personal.

    Inköp är den kärnprocess som påverkar lagerhållningen mest då beslut som tas i inköpsprocessen återspeglas i den bristande lagerhållningen.

    An automated system for assembling cold pressed segments2014Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [en]

    During the spring of 2014, Johan Kooiker and Kashira Roil Beto, students in mechanical engineering at Linnaeus University carried out a degree project together with Husqvarna construction products Sweden AB. The topic of this project was "product development" to develop an automated system for assembling cold pressed segments.

    The project began with studying the current situation to get a clearer picture of the problem and finding out the requirements. The main requirements were studied and implanted in behaviour descriptions of the system. Later on ideas and concepts were generated, which then through rating and screening led to the final concept. The final concept was divided into subsystems and developed in details. The detail work included 3D cad models of unique components and selection of standard component. The final step was to build simple prototypes of the subsystems to test their functions. The prototypes of the subsystems accomplished the main requirements of the company and that led to future investment in final system.

    Hantering av variation för ökad kapacitet i en tillverkningsprocess: Fallstudie på Ballingslöv AB2017Självständigt arbete på grundnivå (högskoleexamen), 15 poäng / 22,5 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Ökad konkurrens tillsammans med allt mer kundspecifika produkter ökar komplexiteten i tillverkningsprocesser. För en långsiktig överlevnad behöver företags produktioner styras väl med ständigt förbättringsarbete, där fokusering på minimering av variation är väsentligt för ett högt kapacitetsutnyttjande.

    Syftet med arbetet var att identifiera hur variation kan hanteras för att höja en tillverkningsprocess kapacitet. En tillverkningsprocess studerades därmed på ett fallföretag för att ge en nulägesbeskrivning som sedan analyserades med teorin. Av analysen kunde orsak och verkan till processens variation antas vilket gav grund för ett experiment. Experimentet utfördes som tre tester där syftet var att undersöka vilka faktorer som minskar variationen samt höjer kapaciteten.

    Resultatet av experimentet blev att variationen kan hanteras med införandet av ett dragande system tillsammans med de förändringar som detta kräver. Kapaciteten som höjdes med den minskade variationen gav inte en total kapacitetshöjning i processen. För att uppnå detta krävdes dessutom att arbetsinnehållet omfördelas mellan de olika processmomenten.

    An Anisotropic Lagrangian Plasticity Model for Semi-crystalline Polymers at Finite Strains2017Ingår i: US National Congress on Computational Mechanics, Montreal, July 17-20, 2017, 2017Konferensbidrag (Refereegranskat)
    Abstract [en]

    The present work concerns modelling of semi-crystalline polymers, such as polyethylene. Semi-crystalline polymers constitute a material group with an increasing industrial importance. Constitutive response (stress-strain relation) as well as fracture properties are of great importance for this class of materials. We propose an anisotropic plasticity model for semi-crystalline polymers, formulated in the reference configuration (Lagrangian formulation). In addition to plasticity, the model accounts for effects of viscoelasticity. The model is evaluated using uniaxial tensile tests, where polyethylene sheets are tested. The model is able to predict the hardening and rate-dependency observed in the experiments very well. Numerical examples are also presented, where the model is applied to a few different geometries

    Anisotropic elastic-viscoplastic properties of at finite strains of of injection-moulded low-density polyethylene2018Ingår i: Experimental mechanics, ISSN 0014-4851, E-ISSN 1741-2765, Vol. 58, nr 1, s. 75-86Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Injection-moulding is one of the most common manufacturing processes used for polymers. In many applications, the mechanical properties of the product is of great importance. Injection-moulding of thin-walled polymer products tends to leave the polymer structure in a state where the mechanical properties are anisotropic, due to alignment of polymer chains along the melt flow direction. The anisotropic elastic-viscoplastic properties of low-density polyethylene, that has undergone an injection-moulding process, are therefore examined in the present work. Test specimens were punched out from injection-moulded plates and tested in uniaxial tension. Three in-plane material directions were investigated. Because of the small thickness of the plates, only the in-plane properties could be determined. Tensile tests with both monotonic and cyclic loading were performed, and the local strains on the surface of the test specimens were measured using image analysis. True stress vs. true strain diagrams were constructed, and the material response was evaluated using an elastic-viscoplasticity law. The components of the anisotropic compliance matrix were determined together with the direction-specific plastic hardening parameters.

    Modeling of damage and crack growth in semi-crystalline polymers2017Ingår i: Proceedings of NSCM 30: The 30th Nordic Seminar on Computational Mechanics, 25-27 October, 2017 / [ed] J. Høgsberg. N.L. Pedersen, DTU Mechanical Engineering , 2017, s. 108-108Konferensbidrag (Refereegranskat)
    Abstract [en]

    t. Crack growth in semi-crystalline polymers, represented by polyethylene, is considered. The material considered comes in plates that had been created through an injection-molding process. Hence, the material was taken to be orthotropic. Material directions were identified as MD: molding direction, CD: transverse direction, TD: thickness direction. Uniaxial tensile testing was performed in order to establish the direction-specific elastic-plastic behaviour of the polymer. In addition, the fracture mechanics properties of the material was determined by performing fracture mechanics testing on plates with side cracks of different lengths. The fracture mechanics tests were filmed using a video camera. Based on this information, the force vs. load-line displacement could be established for the fracture mechanics tests, in which also the current length of the crack was indicated, since crack growth took place. In parallel to the experimental testing, an anisotropic plasticity model for finite strains was developed, which accounts for orthotropic elasticity and orthotropic plastic yielding and hardening. That plasticity model was implemented as a user subroutine in Abaqus. The crack growth experiments were then simulated using Abaqus, using the implemented plasticity model in combination with a damage model. Different types of crack initiation and growth criteria were explored, and the force-displacement-crack length data from the experiments could be well reproduced. Furthermore, the direction-specific work of fracture had been established from the experiments and these energies could be compared to the values of the J-integral from the simulations for the different crack lengths.

    Experimental and numerical assessment of the work of fracture in injection-moulded low-density polyethylene2018Ingår i: Engineering Fracture Mechanics, ISSN 0013-7944, E-ISSN 1873-7315, Vol. 192, s. 1-11Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The fracture mechanics properties of injection-moulded low-density polyethylene (LDPE) sheets were investigated both experimentally and numerically. The total work of fracture was determined experimentally, by means of fracture mechanics testing of sheets of injection-moulded LDPE with side cracks of different lengths. A multi-specimen method, proposed by Kim and Joe (1987), was employed. The total work of fracture was estimated to 13 kJ/m(2). The experiments were simulated numerically using the finite element method. Crack growth was enabled by inclusion of a cohesive zone, and the constitutive response of this zone was governed by a traction-separation law. The local (or essential) work of fracture was estimated through numerical analyses, where the initiation of crack growth was simulated and the outcome was compared to the experimental results. The local (i.e. essential) work of fracture was estimated to 1.7 kJ/m(2), which is consistent with previous experimental measurements for the material in question. The total work of fracture, retrieved from the present experiments, agreed well with the far field values of the J-integral in the numerical analyses.
