The axisymmetric vibration and stability of thick annular plates under internal forces are studied by the finite element method. The internal forces are taken to be the combination of a uniform compressive stress and a pure bending stress. An annular finite element based on a high-order plate theory is used. It has three nodes and 21 degrees of freedom. Accurate estimates of natural frequencies and buckling loads are obtained. The influences of some parameters are studied.
