摘要

In this communication, the state space method is used to analyze the dynamic behavior in Laplace domain of laminated magneto-electro-elastic rectangular plates with viscoelastic interfaces and simply supported boundary conditions based on a Winkler-Pasternak elastic Foundation, and then it is transferred to the time domain by the Fourier inversion method. The Kelvin-Voigt model is used to take into accounted the viscoelastic interface effects. The mathematical formulation is elaborated in a general form and an arbitrary number of layers as well as the orthotropic behavior can be considered. The methodology is based on the mixed formulation, in which basic unknowns are formed by collecting displacements, stresses, electrical displacements, electrical potential, magnetic induction and magnetic potential. As special case, multilayered rectangular plate is analyzed under the surface loading with simply supported boundary conditions based on an elastic foundation. A variant numerical tests shown the effect of the Winkler-Pasternak Foundation on a magneto-electro-elastic rectangular plates dynamic behavior and may contribute to optimize the design and the manufacturing of these materials.
