An investigation was completed on an analysis of an elastic interface edge crack. Specifically, for an edge crack along the interface between two elastic wedges of different opening angles and dissimilar elastic properties, and that is subjected to point loads at the apex, a relation is derived among the length of the crack, the energy release rate of the crack, the applied loads, the wedge angles and the material parameters. The analysis exploits properties of the M-Conservation integral, thereby obviating a consideration of the very complicated associated mixed boundary value problem. jes
