Paper Abstract

The rheological model of new generation, generalizing numerous variants of the multisurfaces theories of plastic flow, is offered to consideration. By virtue of the unique mechanism of cross-links (or, in other words, interaction of plastic yield surfaces) and taking into account reasons of the thermodynamic correctness, it appears possible, within framework of simple (from the point of view mathematics) equations to describe thin qualitative behavior effects of material with shape memory. Even in the elementary case (which is discussed in this article) model allows to describe behavior of ferrous alloys, effects of pseudo-elasticity and the shape memory. The additional offers, permitting jumps in the theory parameters (mathematical analogue of phase transaction) allow more precisely to satisfy with experimental data. This model has shown acceptable results at cyclic deformation.
