Energy damping in shape memory alloys: A review

In recent years shape memory alloys (SMAs) have gained significant attention as potential damping device materials. This article presents an extensive review of the damping characteristics of SMAs, as well as experimental methods used to characterize their damping properties. The shape memory response and associated damping quality are discussed for three popular families of SMAs; Fe-based, Cu-based, and NiTi-based alloys including their behaviors and limitations. This review article also summarizes the most important parameters that impact the damping behavior of SMAs which are necessary to be investigated by researchers and manufacturers to address the current design challenges.
