Shape memory alloys (SMAs) are smart materials showing two unique properties: superelasticity and shape-memory effect. Superelasticity allows SMAs to undergo large deformation upon loading at high temperatures (large strains can be undergone, until 8-10%) and to recover their original shape when unloaded (Figure 1). Shape memory effect is the ability to maintain a deformed shape up to heat induced recovery of the original shape (Figure 2).
