在本文中，开发了具有弹塑性基体和形状记忆合金（SMA）增强的复合材料的等效三相微机械模型。与传统的两相法相比，考虑了奥氏体相、马氏体相和基体相之间的相互作用。模型应用过程中，预测曲线与实验结果吻合良好。最受关注的是纤维形状对复合材料整体响应和残余应力的影响。这对于设计智能复合材料很有帮助。
In this paper, an equivalent three-phase micromechanical model of composite with an elasto- plastic matrix and shape memory alloy (SMA) reinforcement is developed. Compared with the traditional two-phase method, the interaction among the austenitic phase, the martensite phase and the matrix phase is considered. During applications of the model, the predicted curve shows good agreement with the experimental result. Most attention is given to the effect of fiber shape on the overall response of the composite and the residual stress. It is helpful to design an intelligent composite.
