ABSTRACT
This study presents an approximate numerical finite element solution for the higher natural frequencies of circular plates having three different classical boundary support conditions namely, clamped, simply supported, and free edges. The first eighty frequency coefficients are reported and tabulated in the form of table for easy reference, which can be used as benchmark for other alternative methods. In addition, the modal patterns are also graphically demonstrated for showing vibration behaviors.

Keywords : Circular plate, Free vibration, Natural frequency, Finite element method.
