    Abstract: 本文研究含可滲透界面裂紋之雙異質壓電複合層板受反平面均佈應力及平面電位移負載
    時之動力破壞問題,此有限長之界面裂紋假設為可滲透情況之邊界條件。解析時運用
    積分轉換法、柯西奇異積分方程法與切比雪夫多項式展開求得拉普拉斯轉換域下之裂紋尖端的之應力
    強度因子,再利用數值拉普拉斯逆轉換法求得時域中的暫態解。最後,對所求得之數值
    結果做詳盡的分析與討論。
    In this study, the transient response of an interface crack in a piezoelectric layered medium is
    investigated. The composite layered medium is subjected to uniformly anti-plane mechanical impacts and
    in-plane electric displacement impacts under permeable boundary condition. The integral transform, Cauchy
    singular integral equation methods, and Chebyshev polynomial expansions are applied to obtain the solutions
    in the Laplace transform domain. Durbin's method is then used to carry out the numerical inversion of
    Laplace transform. The accuracy of numerical results is examined and the applicable numerical parameters
    are suggested by the experience of calculation. Finally, the numerical results are evaluated and discussed in
    detail.
