Coupled thermo-magneto-mechanical behaviour of ferromagnetic shape memory alloy is
modelled using the theory of thermodynamic of irreversible process with internal variables.
Driving forces acting on twin boundaries and on domain walls are studied for Ni–Mn–Ga
alloys subjected to magnetic and/or stress actions. Evolutions of volume fractions and ratio
of magnetic domain width of two twinned martensites during their rearrangement are
particularly examined.
