✦ Synopsis

The present paper deals with an approximate solution of the title problem in the case of (a) a concentric circular support and (b) a secant support. Fundamental frequency coefficients are determined by means of the Rayleigh minimization procedure; the modal shapes been approximated by simple polynomial co-ordinate functions. In the case of a circular plate with a secant support an independent solution is obtained by means of a finite element code and very good agreement is shown to exist.
