Abstract
A new stress function for an interface crack between two dissimilar elastic half planes which are subject to uniform tension is proposed in this paper. Figures and tables are used to show the relation of the elastic characteristics of the both materials and the maximum stress concentration ratio, or the relation of the J-integral value that was given by a conventional solution and that obtained by this study. The character of this function consists of finite stress concentration with no oscillations at the crack tips, although the elastic solution is used. It is introduced that the behavior of the J-integral values obtained by proposed function are stable for the crack extension, so that this function is suitable for using in numerical simulation of fracture phenomena.
