摘要：

The title problem has been examined using (a) energy-type analyses involving the assumption of modal forms and (b) an alternative finite difference formulation of the governing differential equation of the problem. Because of its simplicity in use and accuracy-the latter method is advocated. Over the entire range of symmetric supports (viz. four-corner supports to one single central support) the finite difference method gives satisfactory results agreeing well with experimental data. © 1969.
