Abstract

Abstract

A mechanical model was established for mode Ⅱ interfacial crack static growing along an elastic-elastic power law creeping bimaterial interface.For two kinds of boundary conditions on crack faces,traction free and frictional contact,asymptotic solutions of the stress and strain near tip-crack were given.Results deriv ed indicate that the stress and strain have the same singularity,there is not the oscillatory singularity in the field;the creep power-har dening index n and the ratio of Young's module notably influence the crack-tip field in region of elastic power law creeping material and nonly influence distribution of stresses and strains in region of elastic material.When n is bigger,the creeping deformation is dominant and stress fields become steady,which does not change with n. Poisson's ratio does not affect the distributing of the crack-tip field.
