Abstract

An analysis of the in-plane biaxial loading of two dissimilar materials with a crack along their common interface is considered. The elastic solution is obtained by the application of the complex variable technique coupled with the principle of superposition. The stress and displacement fields near the tip of the crack are described and the influence of the load parallel to the crack direction is shown. Then a failure criterion is formulated to discuss the debonding along the interface or the brittle fracture of the elastic system. In particular the effect of the non-singular terms on the critical applied tensile stress and on the deviation of the interfacial crack into one of the adjacent media is analyzed.
