The well-known martensitic transformation is the main feature for almost all shape memory alloys (SMAs) usage. Meanwhile, the practical implementation of SMA in devices is not straightforward due to the evolution of their functional properties in ope

Fatigue in shape memory alloys is one of the crucial aspects of their behavior; however, the current knowledge is mainly focused on uniaxial fatigue and is inadequate for engineering purposes. In this article, a fatigue criterion based on the stabili
