Essay

The thesis is devoted to the development of the model for ultimate exhaustion of local plasticity in its application to methods for determination of the cyclic life and damage kinetics of structural materials.The cyclic stress-strain curve equation, which describes the evolution of the elastoplastic behavior of the material from the beginning of loading up to fracture, is proposed. A solution to the problem on distribution diagram of the elastoplastic SSS in cyclic bending has been obtained. Moreover, a scheme for solution of the problem of the kinetics of elastoplastic SSS in the stress concentrator for the material, which changes its properties with an increase in operation time, has been developed.
