WebbShape Memory Alloy. The term shape memory alloy (SMA) normally refers to alloys that can undergo large strains, effect called superelasticity or pseudoelasticity; and also to … WebbShape Memory Alloys (SMAs) are part of the smart materials [14]. The SMAs are able to „remember‟ a shape constituted in advance [15]. This shape is the permanent shape. SMAs sense an external stimulus and respond to it by changing their physical properties which results in a deformation or deflection of the structure [11].
