In this study, transient waves propagating in a functionally graded piezoelectric laminate subjected to uniform anti-plane mechanical and in-plane electric displacement impacts were investigated. An integral transform method was applied to obtain solutions of shear stresses and electric displacements in the Laplace transform domain. The Durbin method was then used to implement numerical inversion. The accuracy of the numerical results for the shear stress at the interface was examined, and superior parameters for Durbin inversion were suggested. The results show that the functionally graded parameters of the two-layered functionally graded piezoelectric material can either increase or decrease the values of the transient shear stresses.
