Paper Abstract
Magnetic Shape Memory Alloys (MSMAs) are promising high-frequency active materials for actuation, sensing,
shape control, vibration suppression and energy harvesting applications. The macroscopic functionality of MSMAs
originates from the coupled evolution of highly heterogeneous magnetic and elastic domain microstructures.
Microstructure dependence of phase transformations in MSMAs introduces internal variables into the model to
account for strong effects of domain microstructure processes on MSMA properties and varying elastic and magnetic
coupling. Selection of internal variables and their incorporation into constitutive modeling has been done
for the problem of field-induced martensite reorientation. Introducing a new internal variable, the austenitic
volume fraction, the study of field induced phase transformation between the parent and martensitic phases is
performed.
