Book Static and Dynamic Analyses of Plates and Shells

Download or read book Static and Dynamic Analyses of Plates and Shells written by Hou-Cheng Huang and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 203 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past decade or so much has been written on the various attempts to produce efficient, accurate and reliable Mindlin plate finite elements. In the late sixties, a degenerated, Mindlin-type, curved shell element was developed and subsequently many improvements in such elements have been made. Reliability and efficiency in use has always been a major objective. Degenerated shell elements have enjoyed widespread popularity despite certain potential defects, including shear and membrane lock ing behaviour and spurious mechanisms. After introducing the basic foundations of Mindlin-type elements, this book describes these defects and also gives the reasons for their occurrence. Furthermore, the author proposes an approach to overcome these defects. A series of linear benchmark tests are proposed to illustrate the performance of the assumed strain element formulations. The formula tions and applications for material non-linearity are also presented. Both isotropic and anisotropic material models are included together with the results for both static and transient dynamic analyses. Two associated programs are fully documented and provided on floppy discs with test examples. Source codes for the two associated programs are provided: one is for static analysis and the other for dynamic analysis, and the programs can be compiled and run on either a mini or mainframe coniputer via a terminal. The author hopes that this book may provide further impetus in the important research area of plate and shell element technology.

Book Geometrically Exact Modeling and Nonlinear Mechanics of Highly Flexible Structures

Download or read book Geometrically Exact Modeling and Nonlinear Mechanics of Highly Flexible Structures written by Seung-Yoon Lee and published by . This book was released on 2002 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: Large space structures must be designed to be stowed during launch and deployed once on orbit because the cargo space of a launch vehicle is always limited. The considerations about payload requirement, weight constraint, and ease of storage during launching make highly flexible deployable structures the main choice for NASA to build large space structures. However, highly flexible structures are usually made of thin-walled beams and shells and have small material dampings, and hence small loads may cause large deformations and maneuver may lead to destructive large vibrations. When a structure undergoes large displacements, various secondary effects may become significant, and its statics and dynamics may involve many nonlinear phenomena. Hence, nonlinear structural theories that can model large displacements and rotations are needed. Consequently, it is important to derive nonlinear structural theories that can model the large deformations of highly flexible structures and to analyze the static and dynamic behavior of such structures in order to design such structures without full scale testing. In this thesis, we derive geometrically exact beam and shell theories, analyze large static deformations of beams and shells, and perform numerical and experimental studies on the nonlinear dynamics of highly flexible beams. A multiple shooting method and a nonlinear finite element method are used in numerical analyses, and a scanning laser vibrometer is used to perform dynamic testing to verify numerical results and to validate the derived total-Lagrangian beam and shell elements. All numerical and experimental results show that the derived nonlinear beam and shell theories are able to model very large displacements and rotations of beams and shells, and the developed nonlinear finite elements are accurate for performing large deformation analysis of highly flexible structures.

Book The Finite Element Method in Thin Shell Theory  Application to Arch Dam Simulations

Download or read book The Finite Element Method in Thin Shell Theory Application to Arch Dam Simulations written by Bernardou and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: ~his Monograph has two objectives : to analyze a f inite e l e m en t m e th o d useful for solving a large class of t hi n shell prob l e ms, and to show in practice how to use this method to simulate an arch dam prob lem. The first objective is developed in Part I. We record the defi- tion of a general thin shell model corresponding to the W.T. KOlTER linear equations and we show the existence and the uniqueness for a solution. By using a co nform ing fi nite e l e m ent me t hod , we associate a family of discrete problems to the continuous problem ; prove the convergence of the method ; and obtain error estimates between exact and approximate solutions. We then describe the impl em enta t ion of some specific conforming methods. The second objective is developed in Part 2. It consists of applying these finite element methods in the case of a representative practical situation that is an arc h dam pro b le m. This kind of problem is still of great interest, since hydroelectric plants permit the rapid increase of electricity production during the day hours of heavy consumption. This regulation requires construction of new hydroelectric plants on suitable sites, as well as permanent control of existing dams that may be enlightened by numerical stress analysis .

Book Nonlinear Finite Element Methods

Download or read book Nonlinear Finite Element Methods written by Peter Wriggers and published by Springer Science & Business Media. This book was released on 2008-11-04 with total page 566 pages. Available in PDF, EPUB and Kindle. Book excerpt: Finite element methods have become ever more important to engineers as tools for design and optimization, now even for solving non-linear technological problems. However, several aspects must be considered for finite-element simulations which are specific for non-linear problems: These problems require the knowledge and the understanding of theoretical foundations and their finite-element discretization as well as algorithms for solving the non-linear equations. This book provides the reader with the required knowledge covering the complete field of finite element analyses in solid mechanics. It is written for advanced students in engineering fields but serves also as an introduction into non-linear simulation for the practising engineer.

Book Peridynamic Differential Operator for Numerical Analysis

Download or read book Peridynamic Differential Operator for Numerical Analysis written by Erdogan Madenci and published by Springer. This book was released on 2019-01-17 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces the peridynamic (PD) differential operator, which enables the nonlocal form of local differentiation. PD is a bridge between differentiation and integration. It provides the computational solution of complex field equations and evaluation of derivatives of smooth or scattered data in the presence of discontinuities. PD also serves as a natural filter to smooth noisy data and to recover missing data. This book starts with an overview of the PD concept, the derivation of the PD differential operator, its numerical implementation for the spatial and temporal derivatives, and the description of sources of error. The applications concern interpolation, regression, and smoothing of data, solutions to nonlinear ordinary differential equations, single- and multi-field partial differential equations and integro-differential equations. It describes the derivation of the weak form of PD Poisson’s and Navier’s equations for direct imposition of essential and natural boundary conditions. It also presents an alternative approach for the PD differential operator based on the least squares minimization. Peridynamic Differential Operator for Numerical Analysis is suitable for both advanced-level student and researchers, demonstrating how to construct solutions to all of the applications. Provided as supplementary material, solution algorithms for a set of selected applications are available for more details in the numerical implementation.
