Auricchio, Ferdinando; Bessoud, Anne-Laure; Reali, Alessandro; Stefanelli, Ulisse A three-dimensional phenomenological model for magnetic shape memory alloys. (English) Zbl 1279.74026 GAMM-Mitt. 34, No. 1, 90-96 (2011). Summary: We present a three-dimensional thermodynamically-consistent phenomenological model for the magneto-mechanical behavior of magnetic shape memory materials featuring a cubic-to-tetragonal martensitic transformation. The existence of energetic solutions for both the constitutive relation problem and the three-dimensional quasi-static evolution problem is proved. The proposed model reduces to some former one via parameter asymptotics by means of a rigorous \(\Gamma \)-convergence argument.
