✦ Synopsis

The in~uence 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!di}erence equations by the Mellin transform technique\ and later to singular integral equations with _xed 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[ Þ 0887 Elsevier Science Ltd[ All rights reserved[
