Method & Evidence

AimHow can the resonant frequencies and vibrational behavior of a sandwich plate structure be modulated through the strategic use of piezomagnetic actuators and functionally graded nanocomposite layers?

MethodAnalytical modelling and numerical simulation

ProcedureA theoretical model was developed based on the first-order shear deformation theory to analyze the forced vibrations of a multi-layered sandwich plate. This model incorporated a metal foam core with varying porosity, functionally graded nanocomposite layers with dispersed Carbon Nanotubes (CNTs), and piezomagnetic face sheets. Governing equations were derived and solved analytically using Navier's method to determine natural and resonance frequencies. The influence of parameters like CNT volume fraction, magnetic and electric potentials, porosity patterns, and layer thickness ratios on the vibrational response was investigated.
