A numerical and experimental study of stress and crack development in kiln-dried wood
2012 (English)In: Proceedings of World Conference on Timber Engineering 2012, 2012Conference paper, Published paper (Refereed)
Abstract [en]

Numerical and experimental investigations were carried out on well defined log-disc samples of Norway spruce consisting of both heartwood and sapwood, with the aim of gaining more adequate knowledge of stress and fracture generation during the drying process. Use of thin discs enabled a well-controlled and simplified drying history of the samples to be obtained. Experiments supported by the numerical model showed the heartwood to dry below the fibre saturation point, much earlier than the sapwood, and thus to start shrinking at a much earlier stage.
