Abstract
In this paper an elliptical crack parallel to a bimaterial interface is considered. The solution utilizes the body force method and requires Green’s functions for perfectly bonded elastic half planes. The formulation leads to a system of hypersingular integral equations whose unknowns are three modes of crack opening displacements. In the numerical calculation, fundamental density functions and polynomials are used to approximate unknown body force densities. The results show that the present method yields smooth variations of stress intensity factors along the crack front accurately. The stress intensity factors are indicated in tables and figures with varying the shape of crack, distance from the interface, and elastic constants. The root area parameter proposed by Murakami is found to be effective for engineering use because different shaped cracks have almost the same values.
