Thermal buckling of graphene platelets (GPLs) reinforced sandwich functionally graded porous (SWFGP) plate with temperature-dependent (TD) properties is investigated. The studied plate is composed of two homogeneous face layers and one functionally graded porous core. Two types of porosity distribution with uniformly distributed GPL reinforcement are included. Based on the first-order shear deformation plate theory, Hamilton principle and Galerkin procedure are employed to build the analytical framework. Uniform, linear, and nonlinear thermal loads along the thickness direction are considered. Subsequently, an iterative procedure is introduced to find out the critical buckling temperature of the plate with the temperature dependence considered. Verifications are conducted to demonstrate the accuracy of the proposed method. Several parametric analyses are investigated in detail where the effects of porosity, GPL weight fraction, geometric configuration, and the boundary condition on the thermal buckling of the plates are discussed.
