Vector J-integral analysis of crack interaction with pre-existing singularities

Abstract:

In this paper, the mechanics of a semi-infinite crack interacting with near crack-tip singularities (e.g., dislocations) in two-dimensional solids is investigated using the concept of potential energy release rate. The spontaneous relationship between the crack potential energy release rate and the well-known vector conservative integral Ji (i=1,2) is derived. It is demonstrated that J1 and J2 integrals are equally import...
