本文以有限元素法探討含有形狀記憶合金(SMA)之方形複合層板中SMA特性對層板挫屈行為的影響。文中探討SMA纖維以APT和ASET兩種不同的方式埋入層板中，並考慮其分佈情況和複合層板疊層方向改變，觀察整體系統挫屈載重的變化。結果顯示使用ASET方法對結構的影響大於APT方法許多，且SMA纖維含量和預應變越多，其產生回復應力越大，使得挫屈載重大幅提升。而SMA纖維越集中於承受高彎曲作用之層板中心處，亦可有效提升挫屈載重。對於複合層板中SMA疊層之勁度相對於其他疊層之勁度較低時，將導致SMA對於整體挫屈行為變化所產生的效應越不明顯。

The effect of shape memory alloy (SMA) on the buckling behavior of a rectangular composite laminate was investigated by Finite Element Method. The influence of SMA on buckling of composite laminates by varying the SMA fiber spacing was studied. Two ways to embed SMA fibers into composite laminates (namely: Active Property Tuning (APT) method and Active Strain Energy Tuning (ASET) Method) were considered. The results show that the ASET method is much better than the APT method in improving the buckling performance of the plate. When the SMA fibers are concentrated in the center area of the plate, the buckling load of the plate will be improved significantly. If the stiffness of the SMA layer is lower than other layers, the influence of the SMA on the buckling load of the plate will become subordinate.
