Elastic-plastic analysis of crack on bimaterial interface

The Elastic-plastic Mechanics of Crack Extension

This paper briefly reviews progres~ in the elastic plastic analysis of crack extension. Analytical results for plane strain and plane stress deformation fields are noted, and elastic-plastic fracture instability as well as transitional behavior and combined rate and thermal effects are discussed.

Interface crack between two elastic layers

A semi-infinite interface crack between two infinite isotropic elastic layers under general edge loading conditions is considered. The problem can be solved analytically except for a single real scalar independent of loading, which is then extracted from the numerical solution for one particular loading combination. Two applications of the basic solution are made which illustrate its utility: i...

Tensile Crack Tip Fields in Elastic-ideally Plastic Crystals

Crack tip stress and deformation fields are analyzed for tensile-loaded ideally plastic crystals. The specific cases of (0 1 O) cracks growing in the [1 0 1] direction, and (1 0 1) cracks in the [0, 1, O] direction, are considered for both fcc and bcc crystals which flow according to the critical resolved shear stress criterion. Stationary and quasistatically growing crack fields are considered...

Intersonic Crack Propagation in Bimaterial Systems

This paper describes experimental observations of various phenomena characteristic of dynamic intersonic decohesion of bimaterial interfaces[ Two separate but complementary optical methods are used in con! junction with high!speed photography to explore the nature of the large!scale contact and mach wave formation at the vicinity of running cracks in two di}erent bimaterial systems[ Theoretical...
