Download or read book Static and Dynamic Buckling of Shallow Spherical Shells Subjected to Axisymmetric and Nearly Axisymmetric Step-Pressure Loads Using SATANS-IIA, A Modified Version of SATANS-II. written by Michael D. Shutt and published by . This book was released on 1976 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: A digital computer program for the geometrically nonlinear analysis of totally arbitrarily loaded shells of revolution (SATANS-2) was modified to more accurately account for the conditions at the pole of the shell. This program was used to determine the buckling load of shallow spherical shells of various sizes when subjected to static axisymmetric, dynamic axisymmetric, and dynamic nearly axisymmetric step-pressure loads of infinite duration. A comparison was made between the new buckling results and previous results obtained without the new pole routine. The comparison revealed a significant change in the buckling pressures, due solely to the change in the pole routine. The new static axisymmetric, dynamic axisymmetric, and even the dynamic asymmetric critical buckling pressure loads appear to be fairly reliable results for perfect, shallow shells.

Book Synopsis Dynamic Buckling of Shallow Spherical Caps Subjected to a Nearly Axisymmetric Step Pressure Load by : John Alan Burt
Download or read book Dynamic Buckling of Shallow Spherical Caps Subjected to a Nearly Axisymmetric Step Pressure Load written by John Alan Burt and published by . This book was released on 1971 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: The behavior of shallow spherical caps subjected to axisymmetric and nearly axisymmetric step pressure loads is examined using a digital computer program for the geometrically nonlinear analysis of arbitrarily loaded shells of revolution. A criterion for dynamic buckling under the nearly axisymmetric load is proposed and critical buckling pressures are determined for both loading conditions for a large range of cap sizes. A numerical convergence study is conducted to verify the accuracy of the results. (Author).

This book was released on 1969 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this report's analysis is to develop a numerical method and computer program for the calculation of the large deflection dynamic response of simply supported shallow spherical shells subjected to a class of spatially asymmetric and timewise step loadings. The program is then used to calculate asymmetric dynamics buckling loads for a few geometries and load durations, which is of importance in the design of spacecraft structures.

Book excerpt: The feasibility of utilizing mathematical programing techniques for determining stable equilibrium states of nonlinear structural systems is explored. The physical problem chosen for evaluation of this methodology was the nonlinear behavior of a shallow spherical shell subjected to uniform pressure. The procedure found most useful was a hybrid method consisting principally of a generalized Newton-Raphson technique with intermittent application of the conjugate-gradient search technique. The variation of buckling pressure with changes in edge restraint and shell geometry is found for a uniformly loaded shell.

This book was released on 1972 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study of the buckling of thin shells was conducted using a digital computer program for the geometrically nonlinear analysis of arbitrarily loaded shells of revolution. The objective was an evaluation of the program's applicability to bifurcation buckling and imperfection sensitivity analysis. Clamped spherical caps under pressure loading and clamped truncated hemispheres under axial tension were investigated. Buckling loads were determined for axisymmetric and nearly axisymmetric loads and are compared with previously published analytical results based on geometric imperfections.

Available in PDF, EPUB and Kindle. Book excerpt: A theoretical investigation of the axisymmetric buckling of complete thin-walled spherical shells under uniform external pressure is undertaken to determine the effect of axisymmetric initial imperfections. In the analysis, the complete spherical shell is divided into two parts; the shallow cap in which the initial imperfection exists, and the remaining portion of the shell most of which deforms in simple contraction. The rotation of the meridian of the cap is assumed in the form of a polynomial function. Four matching conditions are enforced at the juncture of the cap and remainder. The total potential energy of the complete spherical shell is minimized in accordance with the Rayleigh-Ritz approximation method. Two types of initial imperfections are studied; one is an axisymmetric dimple, and the other is a spherical region whose radius of curvature is greater than that of the perfect spherical shell. The maximal values of the pressure parameter rho in the equilibrium state before snap-through were calculated for various values of the geometric parameter lambda, which is proportional to the angular extent of the imperfection for a given radius-to-thickness ratio, and the imperfection amplitude parameter delta, which is the ratio of the initial deviation of the shell mid-surface at the axis of rotation to the wall-thickness. The results of numerical computations show that for all values of delta the lowest buckling pressure is reached when lambda is about 4. (Author).

Book Synopsis Dynamic Buckling of Axisymmetric Spherical Caps with Initial Imperfections by : Robert Kao
Download or read book Dynamic Buckling of Axisymmetric Spherical Caps with Initial Imperfections written by Robert Kao and published by . This book was released on 1977 with total page 41 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dynamic buckling loads are obtained for axisymmetric spherical caps with initial imperfections. Two types of loading are considered, namely, step loading of infinite duration and right triangular pulse. Results show that initial imperfections do indeed have the effect of reducing the buckling capacity for both dynamic and static responses. Solutions also indicate that pulse duration has a very significant impact on the magnitude of the dynamic buckling load, and that the step loading of infinite duration is the limiting case of a triangular pulse and provides the most severe loading situation for dynamic analysis.
