heal.abstract	When a material exhibits large amounts of plastic deformation before failure, with a continuous evolution of the elastic-plastic boundaries around the crack tip the assumptions made by all criteria based on linear fracture mechanics (LEFM) are no longer valid. The necessary modifications of the T-criterion, for adapting it to elastic-plastic solutions, are presented here together with an illustrative example, comprising the case of the definition of the T-criterion by means of the singular plastic solutions of Hutchinson, Rice and Rosengren, henceforth denoted HRR, together with its mixed-mode extension studied by Shih [1-4]. It was shown that the T-criterion is still valid for elastic-plastic cases provided the components of energy are appropriately defined © 1987 Martinus Nijhoff Publishers.	en
