(eng): We propose a phenomenological model describing stress and temperature induced austenite-martensite transformations in polycrystalline shape memory alloys. Polycrystallinity is treated on the level of finite elements. Each element is considered as a single grain of the material with a random orientation. We present various computational results demostrating hysteresis effects.

(cze): Navrhli jsme model popisujici napetim a teplotou indukovanou transformaci v polykrystalickych materialech s tvarovou pameti. Polykrystal je popsan na urovni prvku. Kazdy konecny element je popsan jako jednoduchy krystal s nahodnou orientaci. Presentujeme ruzne numericke experimenty
