This study explores free vibration of a rectangular plate composed PU closed-cell foam enhanced with GNPs and MWCNTs. The governing motion equations are derived based on first shear deformation theory in conjunction Hamilton's principle, then solved by finite element method. Biot's constitutive law for poroelastic behavior is utilized place conventional Hooke's to consider fluid-saturated nature pores. In contrast majority previous studies those were using the Halpin–Tsai micromechanical model, which presumes an unrealistic ideal uniform distribution nanofillers within matrix, modified model used. this method, leveraging existing experimental data employing GA, exponential shape factor parameter corresponding different GNP MWCNT ratios determined achieve best R-squared fit data. Comprehensive analysis various parameters undertaken, encompassing geometric parameters, porosity across patterns boundary conditions. Furthermore, considers influence weight fraction, diverse ratios, reinforcement pattern. obtained results showed that increasing coefficient from 0 0.9, natural frequency reduced about 36.5%, regardless reinforcement. addition, Skempton increased 5.3%. Also, caused greatest decrease frequency, dropping 36.3% as 0.9.
