Abstract

In this paper a moisture-stress analysis based on a 3D orthotropic-viscoelastic-mechanosorptive model for wood is performed by using the Abaqus FEM code. The constitutive model and the needed equations of moisture flow are implemented into some Abaqus user subroutines. The method, which was previously validated with respect to existing experimental data on small wood specimens and glulam cross sections, is used for the moisture-stress analysis of a dowel-type joint under natural relative humidity.
