Numerical Analysis of Moisture-Related Distortion in Sawn Timber
Chalmers University of Technology.ORCID iD: 0000-0001-5591-1045
1999 (English)Doctoral thesis, monograph (Other academic)
Abstract [en]

A 3D theory for the numerical simulation of deformations and stresses in wood during moisture variation is described. The constitutive model employed assumes the total strain rate to be the sum of the elastic strain rate, the moisture-induced strain rate, the mechano-sorption strain rate and the creep strain rate. The 3D theory used for analyzing the shape stability of sawn timber was implemented in a finite element program. To illustrate the types of results that can be obtained, the behaviour of boards during drying was simulated. .....
