A model for studying the martensitic variant pattern in ferromagnetic shape memory alloys (FSMAs) and its evolution is developed. In a departure from prior work, the model allows for complete three-dimensional description of the second-order phase transformations in FSMAs under multiaxial loading. T

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
Previous studies by the authors and their co-workers show that the structure of equations representing shape Memory Alloy (SMA) constitutive behaviour can be very similar to those of rate-independent plasticity models. For example, the Boyd-Lagoudas polynomial hardening model has a stress-elastic st
