Fracture of a composite medium is studied by considering the problem of a mode III crack terminating at a wedge-shaped inclusion. The inclusion is asymmetrically oriented with respect to the plane of the crack and consists of bonded dissimilar materials. Special cases of the problem correspond to a crack lying along the interface of two bonded materials or a crack at an arbitrary angle to a straight interface. The radial and angular dependence of the stress field upon material inhomogeneity is described in detail and illustrated for a variety of geometries. The implications of these results with regard to the prediction of crack propagation are discussed.
