Abstract

In the present work, families of equivalent singe layer and layer-wise models for the static and freevibrations analysis of magneto-electro-elastic multilayered plates are developed. The models are definedin the framework of a unified formulation, which offers a systematic approach for generating refinedplate theories through suitable expansions of the through-the-thickness components of the relevantfields, considering the expansion order as a free parameter. The key features of the developed formulationare: a) the condensation of the electric and magnetic description into the mechanical representation,based on the quasi-static electric-magnetic approximation, which allows to reduce thecomputation of the analysis for both layer-wise and equivalent single layer models; b) the employmentof the Reissner Mixed Variational Theorem, in which the displacements and transverse stress componentsare used as primary variables, thus allowing the explicit fulfilment of the transverse stress interfaceequilibrium. The proposed methodology is assessed by generating different layer-wise and equivalentsingle layer models for the analysis of thick magneto-electro-elastic plates and comparing their solutionagainst available three-dimensional analytic results.
