This paper presents a multi-dimensional thermomechanical constitutive model for shape memory alloys (SMAs). This constitutive relation is based upon a combination of both micromechanics and macromechanics. The martensite fraction is introduced as a variable in this model to reflect the martensitic t

## Abstract We present a three‐dimensional thermodynamically‐consistent phenomenological model for the magneto‐mechanical behavior of magnetic shape memory materials featuring a cubic‐totetragonal martensitic transformation. Existence of __energetic solutions__ for both the constitutive relation pr
In this work, we develop a non-local and thermo-mechanically-coupled constitutive model for polycrystalline shape-memory alloys (SMAs) capable of undergoing austenite $ martensite phase transformations. The theory is developed in the isotropic metal-plasticity setting using fundamental thermodynamic
