The study reviews the developed model of deformations accumulation and depletion of the metal plasticity reserve at the cyclic fatigue life stage. Such model is based on the ideas relating to the index of stress state scheme and consistent in terms of physics. It is shown that the type and numerical value of deformation parameters vary widely depending on the degree of hardening and the tensor of inheritable residual stresses. The experimental study was carried out with the calculations to follow and it is shown that a set of methods developed in a context of a loading history is highly reliable.
