Abstract :Differential Quadrature Method insert ignore into journalissuearticles values(DQM); is employed to obtain natural frequencies and mode shapes of nonhomogeneous rectangular orthotropic plates of linearly varying thickness resting on two -parameter foundation insert ignore into journalissuearticles values(Pasternak);. The analysis is based on classical plate theory. Numerical results are presented for various values of plate parameters for different boundary conditions. Convergence studies have been made to ensure accuracy of the results. A comparison of our results with those available in the literature shows the versatility and accuracy of DQM
