This book was released on 1962 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: A small-deflection analysis is developed for the elastic interbay buckling of ring-stiffened cylindrical shells in which the influence of the rings on deformations before an during budkling is considered. Tests were carried out with a machined, ring-stiffened cylinder (BR-4B) subjected to external hydrostatic pressure Collapse was initiated by elastic asymmetric buckling of the shell. Strain easurements taken during the test demonstrated that the South ell method of determining buckling strength nondestructively is applicable in the case of interbay buckling. The results of this and three other tests of machined cylinders are in good agreement with the theory. While the Von Mises theory is inaccurate for closely spaced rings, its continued application for estimating elastic buckling strength is probably justified since it is always conservative and can be represented in a simple form.

Available in PDF, EPUB and Kindle. Book excerpt: The object of this book is to clarify the whole aspect of the basic problems concerning the elastic stability of of circular cylindrical shells under typical loading conditions. The book deals with buckling, postbuckling and initial postbuckling problems under one of the three fundamental loads, that is, torsion, pressure and compression. The emphases are placed on the accurate analysis and comprehensive numeral results for the buckling problem, experimental verification of the theoretical analysis for the postbuckling problem and clarification of the range of applicability of the perturbation method for the analysis of initial postbuckling behaviors and imperfection sensitivity. The problems under typical combined loads as well as the influence of the contained liquid are also clarified.

Download or read book Plastic Axisymmetric Buckling of Ring stiffened Cylindrical Shells Fabricated from Strain hardening Materials and Subjected to External Hydrostatic Pressure written by Myron Edwin Lunchick and published by . This book was released on 1961 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: A cylindrical shell stiffened by uniformly spaced transverse rings and subjected to external hydrostatic pressure is analyzed for plastic buckling in the axisymmetric mode. In this analysis strain-hardening of the material is accounted for and Poisson's ratio is treated asA VARIABLE WHICH VARIES FROM ITS VALUE IN THE ELASTIC STATE TO AN UPPER LIMIT OF 1/2 FOR INCOMPRESSIBLE MATERIAL. The differential equation for the plastic range is derived for axisymmetric buckling. Expressions for the plastic axisymmetric buckling pressures are obtained. A criterion of length of shell for long and short cylinders is presented, below which the shell can buckle in only one half wave. As a special case of the problem considered, a solution for the plastic buckling of a long cylinder under end compression is obtained. This solution degenerates to that previously obtained by Gerard for a Poisson's ratio of 1/2 but represents a more rigorous solution in terms of variable Poisson's ratios. Limited experimental evidence is presented in support of the theory. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Powered submersibles have enabled the exploration of lake and ocean depths, and are used extensively for inspection of drilling rigs and offshore pipelines. Their potential for the discovery of undersea mineral resources is widely acknowledged.The design of such vehicles poses many problems not encountered with land-based systems: for example, normal pressures are very large, and many structural elements are extremely sensitive to initial geometric imperfections.Following a review of the history and development of submersibles, each chapter concentrates on a specific geometric design. The bibliography is unusually complete, and includes summaries of many referenced publications.This unique book covers all aspects of the structural mechanics, analysis and design of submersibles, and will be invaluable to ocean engineers, naval architects and graduate students entering the field.

This book was released on 1950 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: A strain-energy solution of the buckling of a circular cylindrical shell reinforced by evenly spaced circular ring frames of equal strength under hydrostatic pressure was obtained in Part I. The buckled shape was assumed to be sinusoidal with inflection points at the location of the ring frames. For several geometrical configurations the critical pressure was found to be from two to three times that given by the von Mises solution. The assumed buckled shape used in Report I was modified to permit the inflection points of the deformed shape to occur between ring frames. For the geometrical configurations calculated in Report I, the critical pressure was found to be about one and one-third times that given by the von Mises solution. This represents a marked improvement over the solution obtained in Report I. (Author).
