Abstract

A realistic model for interface cracks is one in which the bond in a small zone near the crack tip is allowed to yield under the high stresses that are to be expected near the interface flaw. Since this yielding may be assumed to take place in an infinitesimally thin zone (the interface) it can very conveniently be related to an appropriate distribution of cohesive tractions, which is then defined by the nature of the adhesive bond. The model is based on the assumption that there are bounded normal and tangential cohesive stresses in a zone near the tip of the crack. The paper discusses a relatively simple model for the analysis of bond stresses and deformations near an interface crack between two materials and establishes a criterion for propagation of an interface crack.
