✦ Synopsis

The three!dimensional stress singularity at the top of an arbitrary polyhedral corner is considered[ Based on the boundary integral equations\ the problem is reduced by the Mellin transform to a system of certain one!dimensional integral equations[ The orders of stress singularity are spectral points of the integral operators while angular distribution and intensity factors are found as residues at those points[ Numerical results are obtained by means of the Galerkin discretization scheme using expansions in terms of orthogonal polynomials with the proper weights[ Some of the results illustrating the order|s dependence on the elastic properties and corner geometry for a wedge!shaped punch and a crack\ for an elastic trihedron and for a surface!breaking crack are given[ Þ 0887 Elsevier Science Ltd[ All rights reserved[ Corresponding author [ E!mail] evgÝkgu[kuban[su[

A stress singularity of type Kr" (6 < 0) exists at the interface corner between bonded elastic quarter planes. The intensity of this stress singularity, referred to here as the free-edge stress intensity factory K,, characterizes the magnitude of the stress state in the region of the interface corne
