Abstract
|
This study supplies a comprehensive exploration of the vibrational response of an advanced doubly curved sandwich panel resting on the Winkler–Pasternak elastic foundation, uniquely designed with a magnetorheological (MR) core and functionally graded piezoelectric (FGP) face sheets enhanced by diverse configurations of carbon nanotubes (CNTs). A power law function is employed to accurately characterize the distribution of FGP properties across the thickness of the face sheets. The micromechanical approach is adopted to derive the equivalent properties of the reinforced FGP layers, considering five distinct CNT distribution patterns as unique reinforcement strategies. The governing equations of the smart sandwich structure under the electric field impact are formulated based on first-order shear deformation theory (FSDT) by implementing Hamilton’s principle. Subsequently, the numerical results are obtained based on Navier’s technique for fully simply supported boundary conditions, utilizing a double-Fourier se
