Abstract
Features of grows on true tension at elasto-plastic strains at static and cyclic loading of structuralmetal materials in connection with their structural state (hardening, softening) are considered in this article. The features of the use of strains and kinetic criterion connected with the bearing capacity of material estimated by extreme plasticity of plastic strains at the time of formation of a neck are shown. It is established that growth of true tension at quasistatic destruction is connected first of all with active accumulation of the residual strains. Methods of strains of nature of behavior of material are described (hardening, softening, stabilization) at cyclic elasto-plastic strains. When loading with the set scope of elasto-plastic strains (tough loading) significant change e tension is observed only in the first (hardening) and the last (softening) cycles. Significant changes in true tension it is observed and directly in loading cycles. It is important to consider the specified changes of true tension when modeling processes of elasto-plastic strains of structural materials and also at the solution of a question of extension of a resource of the designs which fulfilled the resource.
