Abstract
The paper aims to study the interlaminar fracture of lignocellulosic laminate specimens made of beech veneer with urea formaldehyde resin and rye flour under pure mode-I loading. In order to determine the critical value of strain energy release rate GIc, representing one of the material input parameters for a finite element analysis involving the interlaminar fracture behaviour of a laminate structure under complex loading conditions, a lot of double cantilever beam (DCB) specimens processed from a lignocellulosic laminate beech veneer plate were tested by applying the specific standard procedures in conjunction with the modified beam theory method for data reduction. The propagation of interlaminar fracture under pure mode-I was then simulated by finite element analysis using layered conventional shell elements, based on the Virtual Crack Closure Technique (VCCT) in Abaqus/Explicit. Good agreements between the load-displacement curves obtained through the use of finite element analyses and the experimental testing results were obtained.
