Influence of the Plasticity of a Joining Material on the Kink of an Interface Crack at the Corner Point of the Interface of Media

  • Published:
Materials Science Aims and scope

We present the solution of the problem of process zone which develops under the condition of plain deformation from the tip of an interface crack that coincides with the corner point of the interface of two different materials. The process zone is modeled by the line of discontinuity of tangential displacements on the interface and by the lateral line of discontinuity of the normal displacements. The equation for finding the lengths of both discontinuity lines and the expression for the crack opening displacement are obtained. We study the influence of plasticity of the material of the joint on the direction and conditions of crack start.
