"This report describes several types of analyses used to predict the buckling behavior of imperfect shell structures. These analyses are used to study one well characterized stringer-stiffened cylindrical shell. The ability of each analysis to predict the actual experimental buckling load is examined. In addition, the information obtained from each analysis is used when proceeding to a higher level of analysis complexity. Based upon this study, a procedure for calculating a "knockdown" factor is proposed, to replace the traditional empirical knockdown factor."

Thin shells are very popular structures in many different branches of engineering. There are the domes, water and cooling towers, the contain ments in civil engineering, the pressure vessels and pipes in mechanical and nuclear engineering, storage tanks and platform components in marine and offshore engineering, the car bodies in the automobile industry, planes, rockets and space structures in aeronautical engineering, to mention only a few examples of the broad spectrum of application. In addition there is the large applied mechanics group involved in all the computational and experimental work in this area. Thin shells are in a way optimal structures. They play the role of·the "primadonnas" among all kinds of structures. Their performance can be extraordinary, but they can also be very sensitive. The susceptibility to buckling is a typical example. David Bushnell says in his recent review paper entitled "Buckling of Shells - Pitfall for DeSigners": "To the layman buckling is a mysterious, perhaps even awe inspiring phenomenon that transforms objects originally imbued with symmetrical beauty into junk".

Download Buckling of Thin Metal Shells Book in PDF, ePub and Kindle
Thin-walled metal shell structures are highly efficient in their use of material, but they are particularly sensitive to failure by buckiling. Many different forms of buckling can occur for different geometries and different loading conditions. Because this field of knowledge is both complex and industrially important, it is of great interest and c

Download A Review of Imperfection Sensitivity of Stiffened Shells Book in PDF, ePub and Kindle
A short history is related about how imperfections (i.e., deviations from the assumed theoretical form of a shell structure) came to be regarded as the major contributor to the experimental scatter observed in shell buckling tests, and the discrepancy between experimentally determined buckling loads and those determined by classical linear theory. J.M.T. Thompson's insight into the relationship between imperfection sensitivity and optimality of shell structures with respect to load configurations is brought out. The significant contributions to understanding elastic postbuckling behavior of thin stiffened shells and how this work relates to imperfection sensitivity are reviewed. The implications of this work and its applicability to current engineering design and analysis are assessed. The effects of geometric imperfections as well as those induced by boundary conditions or multiple load cases on the postbuckling behavior of shells are discussed. Added discussions by Profs. Singer and van Neut are also presented. (Author).

This collection of papers, written by friends and colleagues of Josef Singer, presents a comprehensive and timely review of the theoretical mechanics of thin shell-structures. Topics of great current interest such as the buckling of composite plates and shells, the plastic buckling of thin-walled structures and the optimum design of buckling sensitive curved composite panels are examined by experts, using a great diversity of approaches, whereby theoretical predictions are compared with experimental results whenever possible.Other topics reviewed include the buckling and post-buckling behaviour of imperfect shells under different external static or dynamic loads and a variety of boundary conditions. Papers dealing with the vibration and the dynamic response of thin elastic bodies are also presented.A strong emphasis is made on the practical applications aspect in the theories presented. Thus engineers, research workers and students who are involved with the design and analysis of shell structures made of different materials, and subjected to various static and dynamic loads will find this volume an invaluable source of reference.

Download Buckling of Conical Shell with Local Imperfections Book in PDF, ePub and Kindle
Small geometric imperfections in thin-walled shell structures can cause large reductions in buckling strength. Most imperfections found in structures are neither axisymmetric nor have the shape of buckling modes but rather occur locally. This report presents the results of a study of the effect of local imperfections on the critical buckling load of a specific axially compressed thin-walled conical shell. The buckling calculations were performed by using a two-dimensional shell analysis program referred to as the STAGS (Structural Analysis of General Shells) computer code, which has no axisymmetry restrictions. Results show that the buckling load found from a bifurcation buckling analysis is highly dependent on the circumferential arc length of the imperfection type studied. As the circumferential arc length of the imperfection is increased, a reduction of up to 50 percent of the critical load of the perfect shell can occur. The buckling load of the cone with an axisymmetric imperfections is nearly equal to the buckling load of imperfections which extended 60 deg or more around the circumference, but would give a highly conservative estimate of the buckling load of a shell with an imperfection of a more local nature.

Download Buckling And Postbuckling Structures: Experimental, Analytical And Numerical Studies Book in PDF, ePub and Kindle
This book provides an in-depth treatment of the study of the stability of engineering structures. Contributions from internationally recognized leaders in the field ensure a wide coverage of engineering disciplines in which structural stability is of importance, in particular the analytical and numerical modelling of structural stability applied to aeronautical, civil, marine and offshore structures. The results from a number of comprehensive experimental test programs are also presented, thus enhancing our understanding of stability phenomena as well as validating the analytical and computational solution schemes presented. A variety of structural materials are investigated with special emphasis on carbon-fibre composites, which are being increasingly utilized in weight-critical structures. Instabilities at the meso- and micro-scales are also discussed. This book will be particularly relevant to professional engineers, graduate students and researchers interested in structural stability./a
