Abstract
<jats:title>Abstract</jats:title><jats:p>The fracture properties of thermally modified beech (<jats:italic>Fagus sylvatica</jats:italic>) wood (TMW) at 180° and 200°C were evaluated in mode II using the three-point end-notched flexure (3ENF) scheme assisted by three-dimensional (3D) stereovision equipment for obtaining displacements and strains. The compliance-based beam method (CBBM) provided the strain energy release rates (<jats:italic>G</jats:italic><jats:italic>II</jats:italic>) of TMW and cohesive laws for both native wood (W) and TMW. Based on the CBBM and equivalent crack length approach (ECLA),<jats:italic>G</jats:italic><jats:italic>II</jats:italic>was...
