A free vibration analysis of isotropic thin circular plate with various edge conditions have been studied in the present work. This study involves the obtaining of natural frequencies by solving the mathematical model that governs the vibration behavior of the plate using finite difference method. The numerical results of natural frequencies of circular plate are presented for different cases such as aspect ratio, curvature effect, grid size and boundary conditions. A good results was obtained from finite difference procedure compared with that obtained from the finite element analysis using Abaqus Package program.
