Nonsymmetric cavity formation at a circular inclusion under remote equibiaxial load
This paper examines the phenomenon of cavity formation through an analysis of the problem of a plane circular elastic inclusion embedded in an unbounded elastic matrix subject to a remote equibiaxial load. Consistent with infinitesimal strain kinematics, nonlinear behavior is confined to a cohesive zone so that inclusion-matrix interaction is characterized by a nonlinear interface force-interface separation law requiring a characteristic length for its prescription. Equilibrium solutions for both rotationally symmetric and nonsymmetric cavity shape are analyzed based on an integral equation formulation together with known elasticity solutions for circular domains.
