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.

Book Synopsis Nonlinear Dynamic Buckling of Spherical Caps with Initial Imperfections by : Robert Kao
Download or read book Nonlinear Dynamic Buckling of Spherical Caps with Initial Imperfections written by Robert Kao and published by . This book was released on 1979 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: A finite difference method is developed for large deformation elastic-plastic dynamic buckling analysis of imperfect spherical caps. The problem formulation is based on governing equations of motion, treating plastic deformation as effective plastic loads. Plasticity theory is derived from von Mises yield condition and Prager-Ziegler kinematic hardening rule which predicts an ideal Bauschinger effect. Results indicate that dynamic effect has the influence of reducing load carrying capacity of perfect spherical caps; however, its influence on imperfect caps depends on the magnitude of initial imperfections.

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).
Book Synopsis The Axisymmetric Buckling of Initially Imperfect Complete Spherical Shells by : Tatsuzo Koga

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 Effect of Fiber Orientation on Initial Postbuckling Behavior and Imperfection Sensitivity of Composite Cylindrical Shells by : N. S. Khot
Download or read book Effect of Fiber Orientation on Initial Postbuckling Behavior and Imperfection Sensitivity of Composite Cylindrical Shells written by N. S. Khot and published by . This book was released on 1970 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: Koiter's approach is used to formulate the influence of fiber orientation on the behavior of the cylindrical shell in the initial postbuckling region. Results are presented for three-layer composite cylindrical shells of either glass-epoxy or boron-epoxy subjected to uniform axial compressive load. The results show that the initial postbuckling coefficient that characterizes the extent of imperfection sensitivity of a structure is greater for the glass-epoxy shells than for the boron- epoxy shells. For the glass-epoxy cylinders the slope of the load vs. end-shortening curve in the initial postbuckling region is found to have high negative value, which is not significantly affected by the change in fiber orientation. This suggests that the buckling of a nearly perfect glass-epoxy cylinder under prescribed end-shortening will be catastrophic, regardless of fiber orientation. However, for the boron-epoxy cylinders the negative slope varies with the change in fiber orientation, and whether the failure will be catastrophic or not will depend on the fiber orientation.

Available in PDF, EPUB and Kindle. Book excerpt: Nonlinear Analysis of Structures presents a complete evaluation of the nonlinear static and dynamic behavior of beams, rods, plates, trusses, frames, mechanisms, stiffened structures, sandwich plates, and shells. These elements are important components in a wide variety of structures and vehicles such as spacecraft and missiles, underwater vessels and structures, and modern housing. Today's engineers and designers must understand these elements and their behavior when they are subjected to various types of loads. Coverage includes the various types of nonlinearities, stress-strain relations and the development of nonlinear governing equations derived from nonlinear elastic theory. This complete guide includes both mathematical treatment and real-world applications, with a wealth of problems and examples to support the text. Special topics include a useful and informative chapter on nonlinear analysis of composite structures, and another on recent developments in symbolic computation. Designed for both self-study and classroom instruction, Nonlinear Analysis of Structures is also an authoritative reference for practicing engineers and scientists. One of the world's leaders in the study of nonlinear structural analysis, Professor Sathyamoorthy has made significant research contributions to the field of nonlinear mechanics for twenty-seven years. His foremost contribution to date has been the development of a unique transverse shear deformation theory for plates undergoing large amplitude vibrations and the examination of multiple mode solutions for plates. In addition to his notable research, Professor Sathyamoorthy has also developed and taught courses in the field at universities in India, Canada, and the United States.
