Abstract

This paper is dedicated to the study of the effect of moisture content on fracture properties of wood through the corresponding effect on the softening function used in cohesive zone model to describe quasi-brittle failure of wood. Bi-linear softening parameters of cohesive zone model are estimated from equivalent linear elastic fracture mechanics resistance curve obtained from a significant number of fracture tests performed in mode I for a wide range of moisture contents (from 5 to \(30\%\) moisture). The evolution of the cohesive zone parameters as a function of the moisture exhibits a moisture dependence of the fracture properties of wood and especially the increase of the cohesive energy related to the crack-bridging phenomenon.
