Fracture prediction of Fe-SMA under monotonic and low cycle fatigue loading

•Investigate the mechanical behavior of Fe-SMA under various triaxiality stress state.•Calibrate fracture parameters of void grow model and cyclic void grow modelfor Fe-SMA.•Conduct microscopic fractography analyses on Fe-SMA under a spectrum of strain amplitudes,•Proposed a modified CVGM capable of predicting LCF fracture of Fe-SMA considering the involvement of different fracture mechanisms.
