Abstract: The study of the behavior of bodies from pseudo-elastic-plastic materials requires the development of special algorithms for calculating the stress-strain state. The work is devoted to the study of the behavior of pseudo-elastic-plastic materials with significant deformations. Pseudo-elastic-plasticity is called the property of materials at high temperature to accumulate deformation of a certain value under loading, and then return to the starting position after unloading through the hysteresis loop. This conversion can be caused by a change in temperature or a change in voltage. The material is also characterized by nonlinear mechanical behavior and high yield stress. This paper provides an analytical review of phenomenological and structural models. A new geometrically nonlinear model is proposed. Alloys that have pseudo-elastic-plastic properties have the ability to restore their former shape. The behavior of such materials under considerable deformations is investigated.
