Elastic Stress Singularity at Interface Edge with Arbitrary Bonding Angle in Dissimilar Linear Hardening Materials.

Abstract

The elastic-plastic stress field near the interface edge with arbitrary bonding angle in bonded linear hardening materials is analyzed, based on the total strain theory and the extended Goursat's stress function. The results show that the stress also becomes singular near the interface edge if the linear hardening is assumed. It is found that the eigen-equation to determine the singular order has the same form as that for the elastic case, where the definition of the Dunders'parameter is modified for the elastic-plastic case.
