通过光弹技术研究了单根形状记忆合金的拔出过程,得到了应力-位移曲线及相变过程,实验结果与记忆合金纤维拔出模型吻合较好.
Photoelasticity technique is employed to examine the pull-out process of a single SMA fiber from an elastic matrix. The force-displacement curves and stress distributions due to martensite transformation are obtained. The experimental results compare favorably with the analytical model.
