Abstract [en]

This test report describes the test arrangement and the results of 4 sets of tensile specimens tested under uniaxial tension. The Aramis 4M optical strain measuring system was used to study the necking phenomena. Strain histories for a large area of the specimen over the entire range of the test are obtained and presented. The manufactures given yield strengths were 235 MPa and 275 MPa, for the nominal thickness's of 4 mm and 6 mm respectively. The specimen dimensions were according to classification society's standards and of non standard geometry. The usage of optical strain measuring system entails very satisfactory information of the whole testing process, respectively the deformation distribution. This report shall serve as a basis reference for future research in the field of metal deformation analysis. True stress versus strain curves can be derived accurately and a comparison between the clamping displacement versus Aramis displacement at a certain point can be made based on the presented results.
