“…Chaabani et al, [2] presented an effective approach to investigating the buckling and post-buckling behavior of porous FGM plates using higher order shear deformation theory. Further, He et al, [3] delved into the nonlinear vibration characteristics and response of a doubly curved shallow shell made of laminated carbon fiber reinforced resin, which had a porous microcapsule coating. This investigation was conducted within a hygrothermal environment and was grounded in the principles of the first-order shear deformation theory; Yang et al, [4] investigated the mechanical properties of FG-GNPRC annular plates with voids in hot and humid environments applying the Newmark method.…”

In this work we studied investigates the nonlinear vibrations of a rectangular saturated porous functionally graded (FG) plate on elastic foundations in thermal environment. The mechanical properties of the saturated porous material vary smoothly with the thickness in three different distributions of porosity including uniform, symmetrically irregular, and asymmetrically irregular. The basic equations are employed by the Reddy’s higher order shear deformation theory, incorporating the geometrically nonlinear von Kármán strain-displacement relationship, stress-strain relations based on the elastic theory for porous materials by Biot, and an analytical solution obtained through the Galerkin method and Airy’s stress function for the simply supported plate. The influence of the geometrical and material parameters, elastic foundations and temperature increment on the nonlinear vibrations of the saturated porous FG plate were specifically evaluated through numerical investigations.
