基于混合物理论，结合Ｔａｎａｋａ的相变描述，给出了小变形、初始各向同性和塑性不可压缩条件下形状记忆合金的三维本构方程。对不同温度下形状记忆合金材料的特性进行了描述，预言了单调及循环加载下的响应和正、反相变行为及其温度影响；动态相变过程对应力响应的影响，高温相下的强度增加等。 Based on the mixture theory and the Tanaka phase transition description, the three-dimensional constitutive equations of shape memory alloys under small, initial isotropic and plastic incompressible conditions are given. The properties of shape memory alloy materials at different temperatures are described, and the response under monotonic and cyclic loading and the effect of temperature on the positive and negative phases are predicted. The effect of dynamic phase transformation on the stress response and the strength at high temperature are increased Wait.
