摘要: 在对形状记忆合金增强复合材料层合板进行应力、应变和温度关系实验的基础上,建立了形状记忆合金增强复合材料四边形和三角形板单元模型,并推导了相应的有限元公式.在此基础上编制了能够进行静态和动态分析的有限元程序,并利用该程序对形状记忆合金增强复合材料悬臂梁进行了分析,结果是令人满意的.随着对形状记忆合金研究的进一步发展,这种材料必将在智能材料和结构设计中发挥越来越重要的作用.

Abstract: Based on a lot of experiments on the thermo-mechanical properties of shape memory alloy reinforced composites, which have already been applied in some intelligent structures, the quadrangular and triangular models are established in this paper, and the corresponding formulae of Finite Element Method are developed accordingly. As the result of these work above, the analytical software for SMARC, including the static and dynamic analysis, is programmed and applied for computing a cantilever structure, which is embedded with the SMA, as an example. The result is quite reasonable. With the development of smart and intelligent materials and structures, it is no doubt the SMARC will play an important role in the future.
