Strain energy release rates of an interfacial crack between two anisotropic solids under uniform axial strain

Abstract

Mode I, Mode II, and Mode III strain energy release rates for a crack lying along the interface of two dissimilar anisotropic elastic solids subjected to uniform axial strain are investigated analytically and also by the finite element method. It is shown that owing to the violent oscillatory crack-tip stress behavior, the strain energy release rates for Modes I, II, and III do not converge to definite values. However, the total strain energy release rate is well defined. A method for separating the effective strain energy release rates for the three fracture modes is suggested.
