Book Description
The elastic deformations of a short, flexible, tapered ring under axisymmetric edge loading and uniform pressure are investigated. The ring is treated as a thin cylindrical or conical shell of short length and linearly varying thickness. A modified Geckeler-type approximation is used for the conical shell. Equations are derived for the elastic behavior of some typical shell junctures utilizing insert rings with tapered sections. A numerical example is given which indicates that maximum discontinuity stresses in a typical reinforced cone-cylinder juncture would be reduced by 33 percent by use of a flexible, tapered ring. The additional highly localized stresses due to notch effects have not been considered. (Author).

Hydrostatically Loaded Structures
Author: W.A. Nash
Publisher: Elsevier
ISBN: 0080534341
Category : Technology & Engineering
Languages : en
Pages : 195
Book Description
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.

Flexible Shells

Publisher: Springer
ISBN:
Category : Science
Languages : en
Pages : 300
Book Description
Euromech-Colloquium Nr. 165 The shell-theory development has changed its emphasis during the last two decades. Nonlinear problems have become its main motive. But the analysis was until recently predominantly devoted to shells designed for strength and stiffness. Nonlinearity is here relevant to buckling, to intensively vary able stress states. These are (with exception of some limit cases) covered by the quasi-shallow shell theory. The emphasis of the nonlinear analysis begins to shift further - to shells which are designed for and actually capable of large elastic displacements. These shells, used in industry for over a century, have been recently termedj1exible shells. The European Mechanics Colloquium 165. was concerned with the theory of elastic shells in connection with its applications to these shells. The Colloquium was intended to discuss: 1. The formulations of the nonlinear shell theory, different in the generality of kine matic hypothesis, and in the choice of dependent variables. 2. The specialization of the shell theory for the class of shells and the respective elastic stress states assuring flexibility. 3. Possibilities to deal with the complications of the buckling analysis of flexible shells, caused by the precritial perturbations of their shape and stress state. 4. Methods of solution appropriate for the nonlinear flexible-shell problems. 5. Applications of the theory. There were 71 participants the sessions were presided over (in that order) by E. Reissner, J. G. Simmonds, W. T. Koiter, R. C. Tennyson, F. A. Emmerling, E. Rarnm, E. L. Axelrad.
