Available in PDF, EPUB and Kindle. Book excerpt: The investigation makes a direct comparison of cylindrical shell panel flutter boundaries obtained analytically with recent experimental boundaries reported in the literature. Further, an attempt was made to explain the discrepancies of the comparison through refinements of some structural aspects of the analysis. The non-linear Donnell shell theory is utilized together with the first-order, high Mach number approximation to the linear potential flow theory. The axisymmetric pre-flutter deformation, due to internal pressurization and axial loading of the shell in the presence of an air stream, is included in the analysis as the configuration about which the shell flutters. The structural boundary conditions assumed for the flutter state are the simply-supported, zero-traction boundary conditions as well as the classical, simply-supported boundary conditions. The problem associated with the pre-deformation state of the shell was solved exactly, whereas the approximate technique due to B.G. Galerkin was employed to solve the linearized system of flutter equations. In general, it is shown that agreement exists between the theory and experiment only in the region of small amounts of static loading of the shell.

Book Synopsis Nonlinear Vibrations and Stability of Shells and Plates by : Marco Amabili
Download or read book Nonlinear Vibrations and Stability of Shells and Plates written by Marco Amabili and published by Cambridge University Press. This book was released on 2008-01-14 with total page 391 pages. Available in PDF, EPUB and Kindle. Book excerpt: This unique book explores both theoretical and experimental aspects of nonlinear vibrations and stability of shells and plates. It is ideal for researchers, professionals, students, and instructors. Expert researchers will find the most recent progresses in nonlinear vibrations and stability of shells and plates, including advanced problems of shells with fluid-structure interaction. Professionals will find many practical concepts, diagrams, and numerical results, useful for the design of shells and plates made of traditional and advanced materials. They will be able to understand complex phenomena such as dynamic instability, bifurcations, and chaos, without needing an extensive mathematical background. Graduate students will find (i) a complete text on nonlinear mechanics of shells and plates, collecting almost all the available theories in a simple form, (ii) an introduction to nonlinear dynamics, and (iii) the state of art on the nonlinear vibrations and stability of shells and plates, including fluid-structure interaction problems.

Book excerpt: A theoretical study was made on the panel flutter characteristics of a ring and longeron stiffened circular cylindrical shell at high supersonic Mach numbers. This study is an extension of an earlier program and uses the cyclic reduction procedure developed there to simplify the flutter analysis. This actual reduction procedure has been included in this report for completeness. An improved modal analysis was employed in this study which leads to an increased understanding of the flutter behavior of such complex structures at the high supersonic Mach numbers. A method for extending the above analysis to the lower supersonic Mach numbers is also discussed. An investigation of the aerodynamic pressures on cylindrical shells in unsteady supersonic potential flow has also been carried out. A general solution for these aerodynamic pressures was obtained which is valid at both the high and low supersonic Mach numbers. The general solution was expressed in terms of Randall functions by reducing the unsteady flow problem to an equivalent steady flow problem through an appropriate transformation. Certain limiting cases of this general solution are presented along with their well-known flat plate counterparts. Finally, an analytical approximation is developed for the Randall functions which would be useful in a cylindrical shell panel flutter analysis. (Author).

Book Synopsis Aeroelastic Vibrations and Stability of Plates and Shells by : Sergey D. Algazin
Download or read book Aeroelastic Vibrations and Stability of Plates and Shells written by Sergey D. Algazin and published by Walter de Gruyter GmbH & Co KG. This book was released on 2014-12-11 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: Back-action of aerodynamics onto structures such as wings cause vibrations and may resonantly couple to them, thus causing instabilities (flutter) and endangering the whole structure. By careful choices of geometry, materials and damping mechanisms, hazardous effects on wind engines, planes, turbines and cars can be avoided. Besides an introduction into the problem of flutter, new formulations of flutter problems are given as well as a treatise of supersonic flutter and of a whole range of mechanical effects. Numerical and analytical methods to study them are developed and applied to the analysis of new classes of flutter problems for plates and shallow shells of arbitrary plane form. Specific problems discussed in the book in the context of numerical simulations are supplemented by Fortran code examples (available on the website).
Book Synopsis Structural Dynamics in Aeronautical Engineering by : Maher N. Bismarck-Nasr
Download or read book Structural Dynamics in Aeronautical Engineering written by Maher N. Bismarck-Nasr and published by AIAA. This book was released on 1999 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: Annotation "Structural Dynamics in Aeronautical Engineering is a comprehensive introduction to the modern methods of dynamic analysis of aeronautical structures. The text represents carefully developed course materials, beginning with an introductory chapter on matrix algebra and methods for numerical computations, followed by a series of chapters discussing specific aeronautical applications. In this way, the student can be guided from the simple concept of a single-degree-of-freedom structural system to the more complex multidegree-of-freedom and continuous systems, including random vibrations, nonlinear systems, and aeroelastic phenomena. Among the various examples used in the text, the chapter on aeroelasticity of flight vehicles is particularly noteworthy with its clear presentation of the phenomena and its mathematical formulation for structural and aerodynamic loads.

Download or read book Recent Contributions to Experiments on Cylindrical Shell Panel Flutter written by W. Horn and published by . This book was released on 1971 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experimental studies have been carried out on the aeroelastic stability of several cylindrical shell configurations under various internal stress and supersonic flow conditions. These experiments were conducted in the AEDC Propulsion Wind Tunnel Facility over the Mach number range 1.2 to 3.5. Some of the initial experiments demonstrated that the still-air buckling characteristics of thin cylindrical shells were not significantly influenced by the supersonic air stream. The wealth of still air buckling data can consequently be employed to determine the buckling loads of cylindrical shells exposed to a supersonic flow field. (Author).
