✦ Synopsis

A variant of the Rayleigh-Ritz method is presented for solving the free vibration problem of annular plates with internal axisymmetric supports. The method is simple, accurate and may be readily programmed and run on a microcomputer. A comprehensive tabulation of the fundamental frequencies is presented for isotropic annular plates with an internal concentric support. Results for full circular plates with concentric supports are also obtained by making the inner radial edge free and permitting the inner radius to become very small.

In this paper, the free vibrations of a wide range of non-uniform rectangular plates in one or two directions are considered. The domain of the plate is bounded by x = a 1 a, a and y = b 1 b, b in rectangular co-ordinates. The thickness of the plate is continuously varying and proportional to the po
