Macromodeling of the magnetic shape memory effect

I shall introduce the simplest 3D model capable of reproducing the complex thermo-magneto-mechanical behavior of a magnetic shape memory alloy crystal featuring a cubic to tetragonal transformation (such as in Ni2MnGa). The model is based on a suitable extension of generalized plasticity. As such its existence will be analyzed within the energetic solvability frame. This is joint work with F. Auricchio, A.-L. Bessoud, M. Kruzik, and A. Reali.
