A number of regularities of deformation and fracture under cyclic loading of structural materials that can be taken into account in modeling the kinetics of damage accumulation and limiting states are considered. The existence of a generalized diagram of cyclic deformation and the deformation-kinetic criterion of destruction is shown, a balance of energy for cyclic deformation and fracture is established.

damage, failure criterion, generalized curve deformation, energy balance, inhomogeneity of deformation
