Abstract
Basic equations and determining relations are given, which determine stressed-deformed plastic state of metal materials taking into account their physical and structural parameters.
The approach to the formulation of defining relationships is based on the inclusion in the number of criterion, along with traditional macro-mechanical, physical and structural parameters. These include, first of all, the parameter of material damage by defects of deformation origin. On the basis of experiments, a connection was established between the stress necessary for the
movement of the blocked dislocation and the measure of damage by deformation microfects, necessary for determining the yield strength and, further, the evolution of the loading surface taking into account the factual factors affecting it. The two-stage stretching tests of the AlMg3 alloy samples showed a significant effect of strain resistance on the stress state.
