ANTIPLANE PROBLEMS OF COLLINEAR CRACKS BETWEEN DISSIMILAR ANISOTROPIC MATERIALS

The antiplane shear problems of collinear cracks at the interface of dissimilar anisotropic materials aredealt with. By using the complex variable method, the formulation for general problem and the solutions in closed form for some of important problems in practice are presented. The stress distribution in the immediate vicinity of the crack tip is examined and the formulas of stress intensity factors are given. The formulations and solutions corresponding to those given in this paper for interfacial cracks in dissimilar isotropic materials, collinear cracks in homogeneous anisotropic and isotropic materials can be derived from the special cases given in this paper.
