This paper researches the free vibrations and corresponding material parameters of a functional gradient graphene platelets-reinforced composite (FG-GPLRC) cantilever torsional plates with both pore variations in transverse direction. Utilizing feature closed-cell cellular solids, mixture rule, modified Halpin–Tsai model, are determined for different volume fractions component materials. Then, using classical plate theory (CLPT), Rayleigh–Ritz technique polynomials, dynamic equation that can be used to obtain vibration mode shapes frequencies rotating is given. Comparison studies previous calculation results from available literature finite element (FE) models conducted, correctness present theoretical formulation numerical verified. Finally, effects platelet (GPL) distribution, porosity distribution (PD), GPL content, rotational speed, average geometric size on system studied depth.
