Available in PDF, EPUB and Kindle. Book excerpt: The purpose of the many examples of buckling presented here is to give the reader a physical feel for shell buckling. Section 1 contains a brief description of two kinds of buckling, collapse and bifrucation. Section 2 concerns shell structures in which the cause of failure is nonlinear collapse due to either large deflections or to both large deflections and nonlinear material behavior. Section 3 gives examples of axisymmetric shells in which failure is due to bifurcation buckling. Section 4 provides examples that illustrate the effects of boundary conditions and eccentric loading on bifurcation buckling of shells of revolution. Section 5 is devoted to combined loading of cylindrical shells and nonsymmetric loading of shells of revolution. Section 6 is on bifurcation buckling and collapse of ring-stiffened shells with emphasis given to cylindrical shells. Section 7 contains several illustrations of buckling of prismatic shells and panels, that is, structures that have a cross section that is constant in one of the coordinate directions. Section 8 focuses on the sensitivity of predicted buckling loads to initial geometrical imperfections. Section 9 demonstrates axisymmetric collapse and bifurcation buckling of bodies of revolution that consist of combinations of thin shell segments and solid segments to which shell theory cannot be applied with sufficient accuracy.

Book excerpt: This report describes the work performed by Lockheed Palo Alto Research Labora tory, Palo Alto, California 94304. The work was sponsored by Air Force Office of Scientific Research, Bolling AFB, Washington, D. C. under Grant F49620-77-C-0l22 and by the Flight Dynamics Laboratory, Air Force Wright Aeronautical Laboratories, Wright-Patterson AFB, Ohio under Contract F3361S-76-C-31OS. The work was completed under Task 2307Nl, "Basic Research in Behavior of Metallic and Composite Components of Airframe Structures". The work was admini stered by Lt. Col. J. D. Morgan (AFOSR) and Dr. N. S. Khot (AFWAL/FIBRA). The contract work was performed between October 1977 and December 1980. The technical report was released by the Author in December 1981. Preface Many structures are assembled from parts which are thin. For example, a stiffened plate or cylindrical panel is composed of a sheet the thickness of which is small com pared to its length, breadth, and stiffener- spacing, and stiffeners the thickness of which is small compared to their _ heights and lengths. These assembled structures, loaded in compression, can buckle overall, that is sheet and stiffeners can collapse together in a general instability mode; the sheet can buckle locally between stiffeners; the stiffeners can cripple; and a variety of complex buckling interactions can occur involving local and overall deformations of both sheet and stiffeners. More complex, built-up structures can buckle in more complex and subtle ways.

Download or read book Thermal Buckling Analysis for Stiffened Orthotropic Cylindrical Shells written by L. K. Chang and published by . This book was released on 1971 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: A theory for thermal buckling of an orthotropic, multilayered, stiffened cylindrical shell is presented. The theory includes the effects of eccentricity of layers and stiffening, and deformations prior to buckling. It is sufficiently general to account for discrete rings and averaged properties of longitudinal stiffening, as well as arbitrary temperature distributions through the thickness of the shell and depth of the stiffeners. Two computer programs are described corresponding to solutions for buckling obtained by using finite differences and determinant plotting or modal iteration. Computed results for thermal buckling of unstiffened and ring-stiffened shells are presented and are in reasonable agreement with published results. The interaction of thermal loading and axial compression in two large diameter stiffened shells representative of a launch vehicle interstage and a preliminary supersonic transport fuselage design is investigated. Results indicate that budding can occur in both structures at a realistic temperature under thermal loading alone.

Available in PDF, EPUB and Kindle. Book excerpt: 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".

Available in PDF, EPUB and Kindle. Book excerpt: "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."

Available in PDF, EPUB and Kindle. Book excerpt: An existing computer program for the geometrically nonlinear analysis of arbitrarily loaded shells of revolution was modified to incorporate initial geometric imperfections into the buckling solution of an axially loaded circular cylindrical shell. Several different boundary conditions were considered, and the predicted buckling loads were examined to determine the significance of the initial imperfections and the boundary conditions for the shell stability problem.

STAGS is intended for the static analysis of arbitrary shells including the effects of nonlinearities caused by material behavior and finite deformations. Collapse loads based on nonlinear analysis can be computed as well as buckling loads based on classical bifurcation buckling theory with linear prestress. Arbitrary thermal and mechanical loadings can be specified. The manual rpovides instructions for use of the code and presents sample problems and solutions. The program is under development and the version presented here is expected to be updated in 1973. The previous report, Volume 1 (AD-751 702), contains the numerical analysis.
