Mechanical Buckling of FG Saturated Porous Rectangular Plate under Temperature Field

In this study buckling analysis of solid rectangular plate made of porous material in undrained condition is investigated. The mechanical properties of plate are assumed to vary through the thickness direction. Distributing of the pores through the plate thickness are assumed to be the nonlinear nonsymmetric, nonlinear symmetric, and monotonous distribution. The effect of pores and pores distribution on critical buckling load of porous plate are studied. Effect of fluid compressibility on critical buckling load is investigated in the undrained condition. Also, effect of temperature on fluid compressibility for symmetric porous material plate, choosing a linear function, is examined. A Direct and analytical method is used for solving governing equations usin Fourier expansion method. The results obtained for porous plates are verified with the known data in literature.
