Abstract:	本文研究雙層功能性梯度壓電複合材料受均佈動力負載之暫態響應，解析一由兩層不同厚度之功能性梯度壓電材料所構成的複合層板，並在上、下表面施加平面正向應力、平面剪應力與平面電位移之均佈動力負載。解析時，先利用拉普拉斯轉換法求得轉換域中的平面正向應力、平面剪應力與平面電位移之解，再利用Durbin之數值拉普拉斯逆轉換法求得時域中的暫態解。數值結果將對不同厚度、不同材料、不同負載頻率及不同梯度變化等作詳細的計算與討論，並驗證本文數值結果之正確性。 In this study, the transient response of a two-layered functionally graded piezoelectric material (FGPM) subjected to uniformly electromechanical impact was analyzed. The layered FGPM composite is constructed by two functionally graded piezoelectric strips of different widths. An integral transform method was applied to obtain solutions of stresses and electric displacements in the Laplace transform domain. The Durbin method was then used to implement numerical inversion. The numerical results for different receivers, different ratios of thicknesses, and different material properties were evaluated and discussed in detail.
