摘要
利用理论和数值方法研究了形状记忆合金增强复合材料的宏细观力学性；能预测复合材料的宏观本构列式和弹性基体约束下的形状记忆合金的相变特性。建立了宏观性能参量与细观相变过程的联系。一维变形状态下的数值结果表明智能复合材料仍然具有形状记忆效应和拟弹性特性，但受到组分材料的性能比、体分比和环境变量等参数的显著影响。
The macro and micro mechanical behavior of smart composite materials reinforced by SMA was described by an analytical and numerical approach. The constitutive relations of the composite and dynamic equations of the SMA transformation were predicted. The numerical results in the uniaxial loading case illustrate the transformation mechanism of SMA under elastic matrix constraint and shape memory effect of the composites. It is shown that properties of the composite are considerably influenced by shape memory effect of SMA as well as the constituent properties, fraction and environment variable such as temperature.
