A Numerical Investigation into the Primary Resonant Dynamics of Magneto-Electro-Thermo-Elastic Plates

Abstract

The geometrically nonlinear forced vibration response of magneto-electro-thermo-elastic (METE) rectangular plates is analyzed herein using a numerical approach. The shear deformation effect is taken into account based on the first-order shear deformation plate theory. The geometrical nonlinearity is also considered using the von Kármán hypothesis. Based upon a variational approach, the energy functional of problem is obtained and represented in matrix form. Then, the variational differential quadrature technique is utilized to directly discretize that functional. For the solution in the time domain, the time periodic discretization method is employed. Finally, the pseudo arc-length continuation technique is used to find the frequency-response curves of METE plates under various boundary conditions. The influences of electric voltage, magnetic potential and temperature difference on the primary resonant dynamics of METE plates are investigated. © 2019, Shiraz University.
