本文以有限元素法探討含有形狀記憶合金(SMA)之方形複合材料層板中形狀記憶合金特性對複合材料層板受氣動力後顫振行為的影響。文中探討形狀記憶合金纖維以不同體積含量及預應變埋入層板中，並考慮複合材料層板疊層方向及形狀記憶合金纖維分佈情況，觀察整體系統顫振行為的變化。結果顯示形狀記憶合金纖維體積含量越多及預應變越大，產生回復應力越大，在完全逆變態的情況下，使得顫振邊界有效提升。而形狀記憶合金纖維越集中於承受高彎曲作用之層板中心處，亦可有效提升顫振邊界。通常臨界動壓力值出現在複合材料層板之第一(1,1)與第二(2,1)模態重合時，但複合材料層板因纖維排列方向及形狀記憶合金特性之影響，使得臨界動壓力會在不同情況下由不同模態合併產生。

The effects of shape memory alloy (SMA) on the linear flutter behavior of square composite laminate plates was investigated by Finite Element Method. The effects of different spacing arrangement of the SMA and prestrain in the SMA on the flutter boundary of the laminate were studied in detail. Results show that with higher initial strain and volume fraction of the SMA will increase the stability boundaries of the laminate. Also, when the SMA fibers are concentrated in the central area of the plate, the stability boundaries will be increased. Because of composite laminate fiber spacing and SMA characteristics, the coalescence pair to yield flutter may between higher modes.
