In order to investigate the effect of loading frequency on stress-strain-temperature relationship in pseudoelastic behavior of Shape Memory Alloys (SMA), tensile tests of TiNi-SMA wire at loading frequencies ranging from 0.001 Hz to 1 Hz were performed, and the stress, strain and temperature of wire were measured simultaneously. Using our proposed thermo-mechanical analytical model of SMA, those pseudoelastic behaviors were simulated numerically as well. Results showed that the loading frequency strongly affects temperature change of the wire and the stress-strain hysteresis loop. The analytical model could predict the time history of stress-strain-temperature relationship with accuracy, and thus the validity of the model has been confirmed. Moreover, by examining the variation of each term of the heat balance equation, the thermo-mechanical mechanism of the pseudoelastic behaviors was also clarified.
