Flexural Vibrations of the Prestressed Toroidal Shell

Abstract

Results of a numerical study of the natural frequencies and modes of vibration of the pressure prestressed toroidal shell are presented. The analysis is based upon a linearized theory of vibrations of prestressed shells. The frequencies and mode shapes are obtained by trial and error in the Holzer fashion. The effects of wall bending stiffness on the frequencies of shells under varying degrees of prestress are shown.
