Abstract :
We develop an energy-based model for polycrystalline shape-memory alloys which allows to predict all relevant features such as pseudoelasticity and the shape-memory effect. The theory is based on orientation-distribution of martensite-variants and the minimization of total elastic strain energy and dissipation due to phase-transformation. Applications in a two-dimensional context are given.
