Article

Numerical experiments are performed to analyze the invariance and reliability of the results of evaluation of the J-integral by the modified method of reactions in problems of mixed fracture. Bodies with cracks undergoing elastoplastic deformation under static loading are considered. To demonstrate the universality of the method to finite-element schemes, prismatic bodies are considered. This allows using not only conventional finite-element schemes, but also the semi-analytical finite-element method
