Abstract
The purpose of this paper is to discuss fracture mechanics basis for the analysis of debonding and delamination in composites. Linear elastic interfacial fracture mechanics theories are reviewed, with emphasis on the modelling and characterization of stress and deformation fields near the edges of debonding and delamination. Relations between stress intensity factors and crack-tip strain energy release rate are presented for a variety of cases. Effects of crack growth, material anisotropy, and crack surface contact and friction are considered in detail. Explicit expressions are given for many important results. Implications of the interfacial fracture mechanics theories to the analysis of delamination and debonding in composite materials are discussed.
