Subject RIV: BM - Solid Matter Physics ; Magnetism
A well established NiTi SMA constitutive model was enhanced so that it accounts for softening of the material response during the phase transition. A characteristic length parameter is introduced and a nonlocal integral averaging technique is adopted in the finite element implementation of the model.
