Energy release rate of fiber/matrix interface crack growth in cross-ply laminates under transverse loading: effect of the 0° /90° interface and of 0° layer thickness
Résumé
Models of Representative Volume Elements (RVEs) of cross-ply laminates with different geometric configurations and damage states are studied. Debond growth is characterized by the estimation of the Mode I and Mode II Energy Release Rate (ERR) using the Virtual Crack Closure Technique (VCCT). It is found that the presence of the 0/90 interface and the thickness of the 0 layer have no effect, apart from laminates with ultra-thin 90 plies where it is however modest. The present analysis support the claim that debond growth is not affected by the ply-thickness effect.
