✦ Synopsis
Absbiet--A new method of analysis is presented for studying the mixed-mode interface crack between dissimilar isotropic materials. The method of approach is formulated on the basis of recently developed conservation laws in elasticity for nonhomogeneous solids and fundamental relationships in fracture mechanics of interface cracks. A solution procedure for the analysis is established and shown to be computationally &cient and operationally simple, involving only known auxiliary solutions and evaluation of conservation integrals along a path removed from the crack tip. An important feature of the present approach is that the crack-tip stress intensity factor solution for each individual fracture mode can be determined accurately and *conveniently by information extracted in the far field. Numerical examples, whose solutions are available in the literature, are presented to demonstrate the accuracy, convergence, and related characteristics of the current approach.
