Abstract : The vibration and radiation characteristics of sandwich-type cylindrical shell structures are investigated. In practical situations the cylindrical structure is subjected to any types of exciting forces. Most of these forces are not describable in any straight forward fashion and some are even random in nature. However, some of the exciting forces can usually be described statistically by correlation functions and power spectra. The purpose of this study is to give a unified presentation of the free and forced vibrations of stiffened and sandwich type cylindrical shells vibrating in water under general types of discrete and random forces.
