Stress Fields for a Crack Normal to and Terminating at a Bimaterial Interface of Isotropic and Anisotropic Half-Planes

Abstract

In this paper, the characteristics of the stress fields for a crack normal to and terminating at a bimaterial interface of isotropic and anisotropic half-planes are studied as a plane problem. The eigenequation, by which the order of stress singularity is determined, is given in an explicit form. It is found that the order of singularity is dependent not only on the elastic constants of the materials, but also on the deformation mode. An explicit closed-form expression is presented for the stress and displacement distribution near the crack tip.
