Abstract
The path independent integral, Ĵ, has been presented as the energy release rate during crack extension. This integral is an extension of the J-integral proposed by Rice and includes the existence of the fracture process region and the effects of plastic deformations, body forces, thermal strains, and inertia of material. In order to show the usefulness of the Ĵ-integral to fracture problems, numerical values of the Ĵ-integral in the presence of body forces, thermal strains, inertia effects, or preloadings that bring about large scale yielding are evaluated. The finite element method is used and illustrative examples are presented.
