Advances on research of SMA superelastic damping for structural vibration energy dissipation

Shape memory alloy is a functional material with characters of shape memory, superelasticity and damping. The energy dissipation, superelastic damping and vibration reduction principal of the shape memory alloy (SMA) are discussed in this paper. New research achievements are introduced. The research results illstrate that the characteristics of SMA are very effective to reduce structural response and have great potential use for efficient energy dissipation devices.
