    Abstract: 本計畫將承續申請人今年度(94)之計畫,擬研究雙層壓電複合材料 之動力破壞問題。申請人今年度之計畫研究了壓電與純彈性複合材料之問 題,而本計畫擬將研究延伸至更複雜且應用性更廣的雙層壓電複合材料之 動力破壞問題。此壓電複合材料乃由兩壓電材料半平面所構成,且電極邊 界型之半無窮長界面裂紋於裂紋面上承受反平面均佈動力點載荷。本計畫 將運用積分轉換法與Wiener-Hopf 法推導此壓電複合材料於拉普拉斯轉換 域中之解,並利用Cagniard-de Hoop 方法來做逆轉換得到時域中的暫態 解,本計畫擬獲得應力、位移、電位能與電位移之暫態全場解,以及動力 應力強度因子與動力電位移強度因子。除外,並將對所推導出的解析解做 數值計算,以與文獻中所能得到之特例問題做進一步比較和詳細討論。
