At the decision of a problem on definition of distribution of J-integral in a compact specimen it is shown, that owing to much spatial character stress-strained conditions distribution of J-integral along front of a crack is essentially non-uniform. Especially it is shown by consideration elastic-plastic deformations. The received results of modelling of development of an elliptic crack in infinite prismatic body coincide with the laws of current of this process described in the literature.
