| 摘 要： | 形状记忆合金一维热力学本构关系中最重要的部分就是马氏体含量ζ的表征。在近年来应用较多的，以Ｔａｎａｋａ，Ｌｉａｎｇ，Ｂｒｉｎｓｏｎ为代表的三种ζ模型的基础上，提出了一个线性的ζ模型，这个模型与试验吻合性较好，并与Ｌｉａｎｇ等人的模型进行了比较、预测精度相差无几，而本模型却很简单。

| Abstract: | The most important part of one dimension constitutive relationship of shape memory alloy is the martensite fraction expression during phase transformation.Basing on the model established by Tanaka,Liang,Brinson which are used in engineering widely,a liner model that concide with experiments is raised,it can be seen that forecasting accuration of the liner model are about the same with hang's,but the linear one is very simple. |
