Mixed multilayered plate elements for coupled magneto-electro-elastic analysis

Finite Elements FE based on the Reissner's Mixed Variational Theorem RMVT, for the analysis of multilayered plates subjected to magneto-electro-elastic MEE fields, are developed in this work.Accurate description of the various field variables has been provided by employing a variable kinematic model which is based on the Carrera?s Unified Formulation CUF.Displacements, transverse shear/normal stresses, magnetic and electric potentials have been chosen as independent unknowns.Interlaminar continuity of mechanical variables is "a priori" guaranteed by the RMVT application.Layer-wise plate elements with linear up to fourth order distribution in the thickness direction have been compared.FE governing equations, according to CUF, are presented in terms of fundamental nuclei whose form is not affected by kinematic assumptions.Results show the effectiveness of the proposed elements, the superiority of mixed FEs with respect to the classical ones, as well as their capability, by choosing appropriate kinematics, to accurately trace the static response of laminated plates subject to magneto-electro-elastic fields.
