Abstract

In this paper, interference between an eliptical inclusion and a crack is considered. The problem is analyzed by the body force method, using a solution for point force doublets outside an elliptical inclusion in an infinite plate as a fundamental solution. Numerical results for the crack tip stress intensity factors are presented for a case of two interface cracks and for a case of a kinked crack, a portion of which lies on the interface. Based on the numerical results, the effects of the geometry and elastic properties of the inclusion on the stress intensity factors are investigated.
