A constrained theory of magnetoelastic materials is applied to study the ferromagnetic shape memory effect in single crystals and polycrystals. The actuation strain induced by domain switching is established first for ferromagnetic shape memory single crystals, from which the strain in polycrystals

## Abstract In the present work we propose a new thermomechanically coupled material model for shape memory alloys (SMA) which includes the two main effects observed for these materials, pseudoelasticity and the shape memory effect. The constitutive equations are derived in the framework of large s
