摘要: Approximate and exact elastic stress analyses are reported for end-notched flexure tests mode II fracture toughness specimens made of composite laminates with adhesive interlayers. Based on the results approximate expressions given data analysis by fitting compliance versus delamination length or direct computation energy release rates. Effects elastoplastic interlaminar shear response sub-critical microcracking type damage also studied. Sizes plastic zones estimated which will be useful choosing specimen dimensions.
