Abstract

The energy dissipation properties of martensite NiTi SMA wires under two different loads, including a quasi-static tensile load and an impact load, are studied through our newly designed testing plants. Meanwhile, by changing the temperature of the SMA wires, the controllability of energy dissipation of the SMA wires is discussed in detail. The results indicate that martensite NiTi SMA wires show excellent energy dissipation capabilities under the loads. It is also found that the energy dissipation properties of the SMA wires can be improved by changing their temperature. The energy dissipation properties of martensite NiTi SMA wires demonstrate that NiTi SMAs have the possibility to be applied in smart automotive safety systems.
