Abstrakt:	The invariance and validity of the evaluation of the J-integral by a modified reaction method in problems of elastoplastic fracture are analyzed based on numerical experiments. Bodies with mode I cracks undergoing elastoplastic deformation under simple static loading without unloading, which corresponds to the deformation theory of plasticity, are considered. To demonstrate the universality of the method of evaluating the J-integral to finite-element schemes, prismatic bodies are considered, which allows using not only the conventional FEM scheme but also the semi-analytic finite-element method (SFEM).
