Free Vibration of Rectangular Composite Plates with Localized Patch Mass

The free vibration of composite plate with various edges condition and carrying distributed patch mass is presented. The Rayleigh_Ritz approach is applied to give frequency characteristic of the rectangular plates. The deflection of the plate is postulated by a double fourier series function. The effect of the various combination of clampad(c) and simply supported(s) edges conditions on the response of plates, is also presented. Finally the results for the simple form of the plate is compared with the results of available in the published literature.
