Comparison of natural frequencies of lamiantes by 3-D theory. II - Curved panels

A 3D vibration study is presented using the 3D theory developed by Chao et al. (1992-1994) for a variety of simply supported shallow spherical, cylindrical, plate, and saddle (hyberbolic) panels in a rectangular planform. A complete survey and comparison of the existing literature is made with excel...

Description
Summary:A 3D vibration study is presented using the 3D theory developed by Chao et al. (1992-1994) for a variety of simply supported shallow spherical, cylindrical, plate, and saddle (hyberbolic) panels in a rectangular planform. A complete survey and comparison of the existing literature is made with excellent lowest frequencies via a 3D augmented energy variational approach. In all of these shell configurations, natural frequencies are noted to decrease in the above-mentioned order according to minimum total potential energy in the natural state. (Author)
