A new version differential quadrature method is proposed to obtain the vibration characteristics of rectangular plates resting on elastic foundations and carrying any number of sprung masses. The accuracy of the technique is demonstrated by comparing the calculated results with the published data. The non-uniform grid spacing is used in this work. The results also demonstrate the efficiency of the method in treating the vibration problem of the rectangular plates carrying any number of sprung masses and resting on the elastic foundations. |
