Abstract: In this paper,an experiment has been conducted to analyze the mechanical propertiesand mechanical parameters of shape memory alloy(SMA) wires with 1 mm diameters,which considering the influencing factors of cyclic numbers,loading rates and pre-strain,so the hysteresis curves,bone curves,secant stiffness and energy dissipation capacity of the SMA wires can be obtained.The results show that the mechanical performance of SMA wires with 30 cyclic numbers at the 0.06 strain value are almost the same ...
