Available in PDF, EPUB and Kindle. Book excerpt: Buckling of thin cylindrical shells from axial impact is studied under the assumption that initial imperfections can be approximated by 'white noise'. Linear small deflection theory is used to calculate the resulting growth of the normal modes and a statistical analysis gives the expected values for the 'preferred' axial and circumferential wavelengths. Very high-speed photographs (240,000 frames/sec) of shells buckling under axial impact show excellent agreement with the theory and demonstrate that large deflection buckling follows the pattern established by the early linear motion.

Available in PDF, EPUB and Kindle. Book excerpt: Investigations dealing with the buckling of thin cylindrical and conical shells subject to axial impact are described. The studies consisted of experimental and theoretical efforts directed toward obtaing a qualitative and quantitative understanding of the dynamic buckling behavior of such shells under a variety of conditions. The conditions studied include different longitudinal conditions imposed on the impacted end of the shell and internal pressurization. In addition, methods of increasing the specific energy dissipation capacity of shells subject to axial impact were studied. A number of interesting results were obtained. It was demonstrated experimentally that buckling of a cylindrical shell is initiated during the first passage of the axial compression stress wave due to the initial impact when the impact velocity is sufficiently high. Another significant experimental result obtained is that the asymmetrical (quasi-developable) form of shell buckling occurs as a result of a smooth transition from the symmetrical ("ring") form of bucklingin some thin cylindrical shells subjected to an axially symmetric axial impact. Analytical subject to a constant velocity end displacement. The method utilizes the finite deflection theory and is a refinement of the procedure due to A.S. Volmir. It shows that both the upper critical stress and the number of circumferential waves increase and the time to initiate buckling decreases with increasing velocity of impact. These trends are in agreement with the analytical results of Volmir and a phenomenological theory due to Coppa.

Available in PDF, EPUB and Kindle. Book excerpt: This book originally appeared as a text prepared for the Defense Nuclear Agency to summarize research on dynamic pulse buckling, by the authors and their colleagues at SRI International, during the period from 1960 to 1980. The original printing of 300 copies by the DNA Press was followed shortly by a small second printing to meet the demand by readers who heard of the book from the primary recipients. This supply was also quickly exhausted, to researchers and practicing engineers outside the DNA community and to academics who wanted to include the material in courses on elastic and plastic stability of structures. Commercial publication by Martinus Nijhoff Publishers was therefore undertaken to meet the needs of this broader community. The objective of the book was to gather into a cohesive whole material that had been published in reports and the open literature during the two decade period. In the process of knitting this material together, a substantial amount of new work was done. The book therefore contains many new results never published in the open literature.

Available in PDF, EPUB and Kindle. Book excerpt: Experimental and theoretical studies of the buckling and collapse of circular cylindrical and conical shells under longitudinal impact are described. Various conditions of loading were investigated such as impact with rigid, fluid, and granular media, and such effects as initial geometrical imperfections, edge support, and loading asymmetry were included. In addition, the effect of axial impact at velocities up to 391 ft/sec on the buckling of thin cylindrical shells was studied experimentally. Finally, three problems, relating to the experiments were studied theoretically: (1) the dynamic buckling of a circular cylindrical shell subject to an exial loading which varies linearly with time, using the nonlinear theory, (2) dynamic buckling of a circular cylindrical shell subject to a constant velocity end displacement, including the effects of plasticity and incorporating extremely large deflections, and (3) the inextensional shortening and collapse modes of conical shells for the complete range of end shortening.

Download or read book Dynamic Stability of Suddenly Loaded Structures written by George J. Simitses and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 295 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dynamic instability or dynamic buckling as applied to structures is a term that has been used to describe many classes of problems and many physical phenomena. It is not surprising, then, that the term finds several uses and interpretations among structural mechanicians. Problems of parametric resonance, follower-force, whirling of rotating shafts, fluid-solid interaction, general response of structures to dynamic loads, and several others are all classified under dynamic instability. Many analytical and experimental studies of such problems can be found in several books as either specialized topics or the main theme. Two such classes, parametric resonance and stability of nonconservative systems under static loads (follower-force problems), form the main theme of two books by V. V. Bolotin, which have been translated from Russian. Moreover, treatment of aero elastic instabilities can be found in several textbooks. Finally, analytical and experimental studies of structural elements and systems subjected to intense loads (of very short duration) are the focus of the recent monograph by Lindberg and Florence. The first chapter attempts to classify the various "dynamic instability" phenomena by taking into consideration the nature of the cause, the character of the response, and the history of the problem. Moreover, the various concepts and methodologies as developed and used by the various investigators for estimating critical conditions for suddenly loaded elastic systems are fully described. Chapter 2 demonstrates the concepts and criteria for dynamic stability through simple mechanical models with one and two degrees of freedom.

Download or read book Dynamic Pulse Buckling of Cylindrical Shells Under Axial Impact written by and published by . This book was released on 1995 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: A series of tests investigating dynamic pulse buckling of a cylindrical shell under axial impact is compared to several 2D and 3D finite element simulations of the event. The purpose of the work is to investigate the performance of various analysis codes and element types on a problem which is applicable to radioactive material transport packages, and ultimately to develop a benchmark problem to qualify finite element analysis codes for the transport package design industry. During the pulse buckling tests, a buckle formed at each end of the cylinder, and one of the two buckles became unstable and collapsed. Numerical simulations of the test were performed using PRONTO, a Sandia developed transient dynamics analysis code, and ABAQUS/Explicit with both shell and continuum elements. The calculations are compared to the tests with respect to deformed shape and impact load history.
