| 摘 要： | 分析了SMA纤维对复合材料梁材料参数的影响，用梁的二维平面单元对含有不同含量和初始残余应变的SMA纤维的复合材料梁进行了有限元分析。计算结果表明，通过激活SMA纤维，对复合材料梁的弯曲和自振频率均有很强的控制和调节能力。

| Abstract: | The influence of SMA fiber on aminated beam's element material parameters is presented. The FEM analysis for a laminated beam with different SMA contents and residual strain is competed by using 2 D plane element. The analysis of deflection and the free vibration shows that the SMA can control the deflection and increase the free vibration frequencies significantly. |
