Abstract
GeneralizedJ-integral is proposed by the author to express three-dimensional fracture phenomena. In this paper we will extend the concept of generalizedJ-integral and proposeJR-integral to be applicable for perturbations of singularities which occur in elliptic boundary value problems. It is shown in Sections 4 and 5 that global energy variation (energy release rate) and local energy variation are expressed byJR-integral.
