    A continuum-mechanical description of the stored energyin shape memory alloys is presented. A rate- independent phenomenological dissipation is then considered to model a hysteretic response. Isothermal simulations with cuALNi single crystal are shown.

    Pomocí mechaniky kontinua popisujeme uloženou a disipovanou energii. Uvažujeme rychlostně nezávislou disipaci a modelujeme tak hysterezi v materiálu. Metoda je testována na příkladu slitiny CuAlNi.
