In this paper, interference between an elliptical inclusion and cracks 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 cracks lying on the interface and for a case of a kinked crack a portion of which lies on the interface. Based on the numerical results, the effect of the geometry and elastic properties of the inclusion on the stress intensity factors are investigated.
