MODELLING COMPRESSION OF WOOD INCORPORATING EARLY WOOD AND LATE WOOD USING THE FEM

Abstract

This paper aims to create a parametric model for wood incorporating early wood and late wood to provide data for the deformation and forces in wood compression perpendicular to the grain. Forces and displacements obtained from the finite element analysis are compared with theoretical prediction and experimental results. The theoretical displacement and stress are calculated by using Hooke’s law, and are compared with the displacement used in tests. The theoretical value of strain obtained in this way equalises the strain obtained in test.
