Abstract

The influence of the geometry of a thin intermediate zone on the stress distribution has been investigated in the vicinity of a crack tip in a bimaterial structure. Corresponding modelling boundary value problems are reduced to functional-difference equations by the Mellin transform technique, and later to singular integral equations with fixed point singularities. It has been observed that the order of the stress singularity is essentially dependent on the model parameters. Numerical results concerning the stress singularity exponents and generalized stress intensity factors are presented.
