STRUCTURAL ANALYSIS AND DESIGN CONSIDERATIONS FOR CYLINDRICAL PRESSURE HULLS

摘要

This report reviews the "state of the art" in the field of pressure hull structural analysis. Equations and formulas developed from consider¬ations of thin-shell theory to describe the elastic and inelastic behavior of ring-stiffened cylindrical shells under the action of hydrostatic pressure are summarized.nNo direct comparison between theory and experiment is included herein; however, only those analyses are included which represent the moat up-to-date knowledge, in the opinion of David Taylor Model Basin structural analysts, and which have found firm experimental confirmation. This presentation should not be interpreted as representing an exhaustive review of all available stress and stability analyses for ring-stiffened cylindrical shells under hydrostatic pressure, but merely one which includes only those formulations which are essential and which have found extensive use in the design of cylindrical pressure hulls.nA few introductory remarks on some of the more promising high-strength hull materials and on new and untried hull configurations and construction techniques presently being investigated at the Model Basin are also presented.
