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.}, pages = {515--522}, title = {繰返し荷重を加えたTiNi形状記憶合金ワイヤの応力ーひずみー温度関係の計測および数値解析}, volume = {69}, year = {2003} }
