The problem of a crack along the interface of an elliptical elastic inclusion is analyzed using a body force method. In the numerical analysis, a fundamental solution for the force acting at a point in an infinite plate containing the elliptic inclusion is used. Based on numerical results, the effects of geometry and elastic properties of the inclusion on the stress intensity factors are investigated.
