A generalization was proposed for the so-called synthetic 2-level phenomenological model of non-linear deformation of polycrystals, for the description of irreversible deformation of shape-memory materials. The model reflected the mutual influence of the processes of deformation, of martensitic and defect-dislocation nature, and took account of the effect of residual micro-stresses upon the deformation process. The applicability of the model to shape-memory materials was confirmed by comparing theoretical results with experimental data from cyclic thermomechanical tests.
