ОЦЕНКА ПРЕДЕЛЬНЫХ ДЕФОРМАЦИЙ ПРИ НЕМОНОТОННОМ НАГРУЖЕНИИ

Abstract

The method of estimation of plasticity of metals is offered at the unmonotonous loading in basis of which a hypothesis is fixed that damages have the directed character and described the tensor of the second grade. In quality a tensor the components of tensor of tensions are chosen. It is accepted that destruction comes subject to the condition, when faltung of tensor of damages equals unit. The condition of destruction is offered d for the estimation of of maximum deformations at deformation on the doublelink trajectories of loading. Dependences of of maximum deformation are on the corner of fracture of doublelink trajectory of loading and from the of degree of deformation before a fracture.
