Cycling model for a NiTi Shape Memory Alloy

Procedia Structural Integrity, 2021
Shape memory alloys are more and more used in many fields of mechanics and medicine. The reason of the success is the ability to recover the initial shape also after high values of deformation. During the deformation, the SMA are able to change the structure from an initial structure, often named as austenite, to a final structure named martensite ...
