✦ Synopsis

A solution for the titular problem is obtained expressing the plate response in terms of polynomial coordinate functions which identically satisfy the boundary conditions only at the outer edge. The plate thickness variation is defined by the functional relation /r(r) = he[l + y(r/a)"]

where n is an integer. The frequency determinant is generated by a straightforward application of the RayleighhRitz method.
