✦ Synopsis

A three-dimensional vibration study is presented using the three-dimensional theory developed by Chao et al. [34}39] for a variety of simply supported shallow spherical, cylindrical, plate, and saddle (hyberbolic) panels in rectangular planform. A complete survey and comparison of existing literature have been made with excellent lowest frequencies via a 3-D augmented energy variational approach. In all of these shell con"gurations, natural frequencies are noted to decrease in the above-mentioned order according to minimum total potential energy in the natural state.

The three-dimensional theory of laminated plates and shells has been developed by Chao et al. [10}13,62,63] with many applications to impact and shock modal analyses. In this research, a complete survey of the literature is made on the free vibration natural frequencies of simply supported rectangul
