Effect of the proximity to the 0°/90° interface on Energy Release Rate of fiber/matrix interface crack growth in the 90°-ply of a cross-ply laminate under tensile loading
Models of Representative Volume Elements 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 using the Virtual Crack Closure Technique. It is found that the presence of the interface and the thickness of the layer has no effect, apart from laminates with ultra-thin plies where it is however modest. The present analysis supports the claim that debond growth is not affected by the ply-thickness effect.
