Interfacial crack-tip field in anisotropic elastic solids
For interfacial cracks in anisotropic elastic solids, controversies exist in that several different definitions for the crack-tip field have been proposed in the literature. In this paper, we first devise a novel and convenient scheme for constructing the interfacial crack fields and then carry out a mismatch analysis for understanding the oscillatory structure of the crack-tip stress singularity. It is hoped that the mismatch analysis can shed some light on the controversial issues from a different perspective. Critical quantities governing the oscillation and mismatch are numerically evaluated for a number of materials including two fiber- reinforced composites and a group of crystals of cubic symmetry.
