The Ritz method is applied in a three-dimensional (3-D) analysis to obtain accurate frequencies for thick circular and annular plates. The method is formulated in a manner which allows one to have any combination of free or fixed plate boundaries. Admissible functions for the three displacement comp

Three-dimensional vibrations of thick circular and annular plates are analyzed by a "nite element method which, with a properly assumed set of displacement "eld, is di!erent from the traditional 3-D "nite element analysis and is reduced to a sequence of 2-D analyses one for each circumferential wave
The title problem is solved using very simple polynomial co-ordinate functions and a variational approach. Rather general boundary conditions are assumed at the edge support. It is shown that the approach is valid jor axi-and antisymmetric modal configurations.
