In engineering applications, all the structural components are subjected to dynamic loading conditions in their working life and the effect of vibration is considerable. Structural components may take the form of a rectangular plate, for such elements the prediction of vibration characteristics becomes important when their associated mode shapes operate closer to resonant modes, stated as a measure of failure. Additionally, the effect of the cutout located in the plate also has an effect on the modal behaviourial characteristics. The research work entitled in this paper focusses on the prediction of the modal vibration characteristics of a rectangular plate applying Finite Element Analysis. The mode shapes of the plate are determined using this base line methodology. Three types of clamped boundary conditions are applied over the plate, Outer periphery constrained without cutout, Outer periphery constrained with cutout, Outer-inner periphery constrained with cutout. The numerical computations carried out for conventional material based Aluminium plate is further extended to Glass Fibre Reinforced Plastic material plate with the same set of boundary conditions applied. From the present study it is noticed that the operating frequencies for both peripheries constrained are more than periphery constrained with and without cutout.
