The Role of Thermomechanical Coupling in the Dynamic Behavior of Shape Memory Alloys
- 181 Downloads
In recent years, shape memory alloys (SMAs) have started to attract increasing attention due to some of their dynamic properties. The hysteretic phase transformation between austenite and martensite at high temperature and between different twins of the martensite phase at low temperature constitutes an intrinsic dissipation mechanism, which results in a considerable damping capacity. Graesser and Cozarelli  suggested the use of SMAs as novel damping materials and Clark et al  demonstrated the feasibility of the concept for a Nitinol wire device. Potential applications are seen for example in civil structures like buildings and bridges needing an efficient seismic base isolation, see Wilde et al .
