本文研究內含界層裂紋之彈壓電複合材料的動力破壞問題，解析一含半無限長電極型界面裂紋之彈壓電複合材料，於裂f文面上施加一對反平面動力點載荷之暫態效應。本文使用積分轉換法及Wiener-Hopf 技巧推導彈壓電複合材料在一次拉氏轉換域中，於裂紋面受空間指數型應力分佈的基本解，並利用所求得之基本解來解析此包含特徵長度的複合壓電材料動力破壞問題，按著使用Cagniard-de Hoop 方法來做拉氏逆轉換得到時域中的解。最後，針對應力與電位移強度因子等解析解做詳細的數值計算與討論。 In this study, the transient response of a semi-infinite interface crack between piezoelectric and purely elastic materials with the electrode boundary condition is investigated. This composite is subjected to dynamic anti-plane concentrated loading on the interface crack faces. Exact transient solutions for dynamic stress intensity factors and dynamic electric displacements intensity factors are derived analytically. Finally, numerical results are evaluated and discussed in detail.
