Free vibration of elastically connected circular plate systems

In a previous paper [1], the authors have presented the solutions for the normal mode vibrations of an n-plate system. In that paper the numerical results were limited to the frequencies and mode shapes of some representative models of double plate systems. In the present paper additional numerical results are presented to illustrate the various other features such as the influence of the thickness ratio and foundation stiffness on the frequencies. The omission of a normal mode of the free-fixed case in the previously published paper is also pointed out.
