✦ Synopsis

An analy'ical sol'tion based on the superposition method is developed for the first time for the free vibration of the title problem. While it will be seen that the line support is replaced by point supرrorts, convergence tests show that a limited number of point supports provide exceflent solution accuracy. Three families of vibration modes are delineated and accurate ei iyenvalues a a '. presented for the first four free vibration modes of plates with a wide range of plate geom tries. Three-dimensional mode shapes are plotted for some typical square plates.
