WebbShape Memory Alloy (SMA) is a metal that can ‘remember’ its geometry, that is, after a sample of SMA has been deformed from its original shape, it regains its original geometry by itself during heating (shape memory effect) or, simply during unloading at a higher ambient temperature (superelasticity). These extraordinary properties are due to a Webb4 apr. 2024 · Shape memory alloy (SMA), a kind of smart material, can be used as an actuator in many fields; however, its strong nonlinearity and parameter uncertainty …
