The problem of limit equilibrium of an elastoplastic body weakened by a crack is considered in the case of simultaneous realization of three macromechanisms of fracture. On the basis of the energy approach and some hypotheses, the criterion equations are proposed for the case of mixed fracture. The comparison of the theoretical and experimental values is presented.
