ABSTRACT
The present paper deals with a comprehensive study of frequency coefficients for natural free vibrations of twenty-one square plates with different edge support conditions. The ANSYS finite element computer program is used for modeling and analyzing the plate vibration problems with a dense net of 10000 elements in order to determine the frequencies numerically. Results concern-ing the frequency coefficients and their corresponding mode shapes are given in the form of graph and table for easy reference, which can be used as benchmarks for other alternative methods.

Keywords : Square plate, Free vibration, Frequency Analysis, Finite element method.
