Coplanar cracks at the interface of bonded dissimilar orthotropic elastic half-planes

Abstract

This paper deals with the problem of determining the stress intensity factors when two coplanar Griffith cracks are located at the interface of two bonded dissimilar orthotropic elastic half-planes. Fourier transforms are employed to reduce the mixed boundary value problem to that of solving a set of simultaneous singular Fredholm integral equations of the second kind. These equations are further reduced, by using Jacobi polynomials, to a system of simultaneous algebraic equations. The stress intensity factors are calculated by using numerical methods.
