By using the energy approach of fracture mechanics, the deformation and force criteria of the state of limiting equilibrium are analytically established for bodies subjected to the combined action of loading and hydrogen. The proposed criteria are well justified from the physical point of view because they consider the case of simultaneous realization of three macromechanisms of fracture and exhaustion of plasticity in the entire process zone. Hence, they can be used for the evaluation of the residual strength of structural elements operating under the conditions of complex stressed state and the action of hydrogen.
