Mechanical buckling of functionally graded (FGM) sandwich plates is analyzed in this research using new higher-order shear deformation plate theory which captures the shear deformation influences needless of any shear correction factor. New functionally graded sandwich structure based on variable exponential function is presented in this analysis. Material properties of functionally graded face layers are assumed to vary continuously through-the-thickness according to an exponential function in terms of the volume fractions of the constituents (E-FGM), while the core layer is made of ceramic. Equilibrium and stability equations of E-FGM sandwich plate with simply supported boundary conditions are derived using the generalized higher-order shear deformation plate theory and the Hamilton’s variational principle, and solved by using the Navier’s solutions. Several numerical results indicate the influence of the plate aspect ratio, the relative thickness, the gradient index and the sandwich scheme on the critical buckling load of FGM sandwich plates are investigated.
