    Résumé (Anglais)) : In this study, a new theory of high-order hyperbolic shear deformation with four variables is presented for the analysis of the vibrational behavior of functionally graduated porous plates. The equations of motion are obtained using the principle of virtual work. The analytical solutions for a functionally graduated plate simply supported and subjected to a transverse load are obtained and determined by Navier solutions. A comparison with the results corresponding to the literature is made to verify the accuracy and effectiveness of the current theory. Keywords: Functionally graded plate; Free vibration; Porosity; Higher-order shear deformation.
