The large deflection of the annular plates with simply supported boundary conditions is analyzed by the finite element method using the nonlinear programming theory. Both fixed-hinged and movable-hinged supports are taken into account, while the line loads or the uniform distributed loads are applied. The distributions of the out-of-plane and in-plane displacements and stress distributions in the radial cross section are presented for some load ratios in six cases. It is concluded that the out-of-plane displacements with movable-hinged supports were smaller than those with the fixed-hinged support, and that the shrinkages between the inner and outer edges in the radial direction were almost the same under the two simply supported boundary conditions.
