A Crack Kinked at the Interface of Bonded Anisotropic Elastic Media under Longitudinal Shear Stresses

Abstract

The stress intensity factors at the tips of a crack kinked at the interface of bonded anisotropic elastic media are analyzed. By using a singular point method, the problem is reduced to solving a system of singular integral equations with generalized Cauchy kernels. The characteristic equation that determines the stress singularity at the kink vertex is derived from the singular integral equations, and singular stress fields at the kink vertex are determined definitely. By taking into account of the stress singularity at the kink vertex, numerical results are given graphically for the stress intensity factors at the tips of the kinked crack.
