| Abstract: | Fatigue properties is one of the most important indicators to evaluate shape memory alloys. In this paper the definition of fatigue behavior of the shape memory alloys is extended. Bending rotation fatigue, as a simple and powerful tool to test the fatigue properties, is presented in detail. The research progress in the fatigue of shape memory effect and super-elasticity is summarized. In addition, the limitation and disadvantage of present study in fatigue behavior of shape memory alloys are discussed. |
