We present results of a numerical simulation of the effect of cyclic creep (ratcheting) with different programs of stress-controlled uniaxial asymmetrical loading of two metallic materials with different cyclic properties. An improvement of the kinematic hardening rule in the cyclic plasticity model on the basis of defining equations of the endochronic theory of plasticity is proposed. It has been shown that the proposed model allows one to describe with satisfactory accuracy the kinetics of the stress-strain state of specimens under low-cycle asymmetrical loading on the basis of the minimum number of basic experiments.
