将ＴｉＮｉ形状记忆合金（ＳＭＡ）薄带复合于基体材料内部，利用形状记忆合金的特性，可以控制构件裂纹的扩展。本文介绍了智能复合构件控制裂纹的机理，并利用拟温度载荷法，直接应用现有有限元程序对控制裂纹的ＳＭＡ智能复合构件进行了计算与分析，同时还进行了激光云纹干涉法试验测试。计算和试验结果表明智能复合构件中的记忆合金薄带对构件裂纹有显著的控制效果，同时计算和试验结果的一致性也表明本文的分析方法是可行的。
The TiNi shape memory alloy (SMA) ribbon composite within the matrix material, the use of shape memory alloy properties, can control the expansion of crack components. In this paper, the mechanism of crack control in smart composite structures is introduced. By using pseudo-temperature loading method, the existing finite element program is applied to calculate and analyze SMA smart composite structures with crack control. At the same time, . The calculation and experimental results show that the memory alloy strip in the smart composite component has a significant control effect on the component crack, and the consistency between the calculated and experimental results also shows that the analytical method in this article is feasible.
