Abstract EN
In this study, a piezoelectric laminate is analyzed by applying the Laplace transform and its numerical inversion, Fourier transform, differential quadrature method (DQM), and state space method.
Based on the modified variation principle for the piezoelectric laminate, the fundamental equations for dynamic problems are derived.
The solutions for the displacement, stress, electric potential, and dielectric displacement are obtained using the proposed method.
Durbin’s inversion method for the Laplace transform is adopted.
Four boundary conditions are discussed through the DQM.
The proposed method is validated by comparing the results with those of the finite element method (FEM).
Moreover, this semianalytical method is further extended to describe the dynamic response of piezoelectric laminated plates subjected to underwater shocks by introducing Taylor’s fluid-structure interaction algorithm.
Both air-backed and water-backed laminated plates are investigated, and the effect of the fluid is examined.
In the time domain, the electric potential and displacements of sample points are calculated under four boundary conditions.
The present method is shown to be accurate and can be a useful method to calculate the dynamic response of underwater laminated sensors.
