Annotation	A computational model for the analysis of the transition of crack across the sharp material interfaces between, in general, orthotropic materials will be presented. The computational model relies upon Betti’s-Rayleigh reciprocal theorem and FEM. Matched asymptotic procedure is adopted to derive the change of potential energy. Higher order terms in the matched asymptotic expansions are considered and a novel approach to the application of reciprocal theorem for calculation of the fracture mode mixity based upon the energy release rate (ERR) for debonding crack is suggested.
