This book was released on 1977 with total page 115 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report deals with the effect of initial imperfections on optimal stiffened cylinders under axial compression. A nonlinear stability methodology is developed for analyzing such system in the presence of small initial imperfections. This methodology is then employed to assess the effectiveness of stiffened cylinders optimized on the basis of linear stability analysis.

Available in PDF, EPUB and Kindle. Book excerpt: A nondimensional chart is presented for the theoretical critical stress in torsion of simply supported cylinders stiffened by identical, equally spaced, torsionally weak rings. The results are obtained by solving the equation of equilibrium by means of the Galerkin method. Comparison of the theoretical results wit hthe experimental results indicates that ring-stiffened cylinders buckle on the average, at a buckling stress about 15 percent below the theoretical buckling stress presented.

This book was released on 1966 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent investigations on the influence of edge conditions on the critical axial load of cylindrical shells are extended here to include cylinders with elastic edge restraint. It is shown that weak edge conditions are unlikely to affect the critical load significantly in experiments or in practice. Also the effects of symmetric initial imperfections were investigated. The critical load for cylinders with initial imperfections in the form of a cosine function was found to be somewhat lower than was indicated in a previous analysis by Koiter. The analysis also disclosed that very short cylinders would not be sensitive to the types of imperfections which were considered. A few tests were performed and their results tend to support this conclusion.

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.
