The uniaxial model, cast within a framework of a general theory of inelastic behavior, is based on a single internal variable (the martensite fraction) for which an evolution equation in rate form is proposed. The response of the model under cyclic stress and/or thermal paths is presented and discussed. Despite its simplicity, the model is able to predict the shape-memory effect and pseudoelastic behavior.
