This paper presents the governing equations and analytical solutions of classical shear deformation theories functionally graded axisymmetric circular plates. The classical, first-order, third-order are presented, accounting for through-thickness variation two-constituent material, modified couple stress effect, von Kármán nonlinearity. Analytical bending linear theories, some which not readily...

In this paper, buckling of the plates is investigated with different boundary conditions and alternating and axial compressive loadings by theoretical approach and numerical analysis with circular and rectangular closed sectional plates. In this research, governing differential equation will be used for thin plates under lateral and direct alternating loadings. Next, the mentioned equation woul...
