Combined model of phase-structural deformation of shape memory alloys

Abstract

A combined model of inelastic deformation of shape-memory alloys for phase and structural transformations is proposed, taking into account the fundamental difference between these two mechanisms and the influence of the first mechanism on the second. In contrast to the known analogs, the model allows for non-monotonic loading processes to exceed the long arc of phase-structural deformation (an analogue of the Odqvist parameter in the theory of plasticity) of the intensity of crystallographic deformation of the phase transition.
