Development of a structural model of deformation with hardening on the basis of distributed dislocations

We consider a problem of elastoplastic deformations with strengthening in the case where a “tooth” of yield is present in the (σ-∈) diagram. On simulation of the process of development of plastic deformations with hardening by using distributed screw dislocations, a conclusion on the existence of a structural parameter is drawn.
