Disappearance Conditions of Stress Singularities for Anisotropic Bimaterial Half-Plane Wedges Under Antiplane Shear

Abstract

Based on the anisotropic elasticity theory and Lekhnitskii’s complex potential functions, the analytical eigenequations of anisotropic bimaterial half-plane wedges under antiplane shear are derived in brief forms. The boundary surfaces of half-plane wedges can be combinations of free and/or clamped edges. The disappearance conditions of stress singularities can be obtained directly from the derived eigenequations, which can be applied to improve the safety of the structures. The interesting phenomenon on the periodic appearance of the singularity orders is proposed and discussed as well.
