Vibration and Stability Analysis of Arbitrary Stiffened Shells of Revolution,
Abstract
This report presents the analytical development of a finite element model suitable for a study of the elastic vibration and stability characteristics of a structure composed of a finite number of shells of revolution, each in the shape of a conical frustum. Thus, the model can be used to study a shell of revolution, with arbitrary meridional cross section, to which is attached arbitrarily shaped circumferential ring stiffeners and lateral bulkheads. The shell theory used to model each conical frustum is a third order Flugge-Lure-Byrne theory in which a complete interaction between shell membrane and bending effects occurs. The finite element models presented herein are to be basic elements in an analysis program designed specifically for use in a program for the automated structural design of submerged stiffened pressure vessels in the form of arbitrary structures of revolution.
