✦ Synopsis

Abatraet-A new numerical method is presented for analysing the mixed-mode interface crack between two dissimilar isotropic materials. The method is formulated on the basis of finite element and the crack closure integral approach in conjunction with fundamental relationships in fracture mechanics. A simple and efficient solution procedure is developed involving only known auxiliary solution for evaluating the strain energy release rate. The finite element solution converges to accurate solution for small crack extensions. Numerical examples are presented to demonstrate the accuracy of the proposed approach.
