This book was released on 2012-12-06 with total page 533 pages. Available in PDF, EPUB and Kindle. Book excerpt: Starting in 1996, a sequence of articles appeared in the Journal of Nonlinear Science dedicated to the memory of one of its original editors, Juan-Carlos Simo, Applied Me chanics, Stanford University. Sadly, Juan-Carlos passed away at an early age in 1994. We lost a brilliant colleague and a wonderful person. These articles are collected in the present volume. Many of them are updated and corrected especially for this occasion. These essays are in areas of scientific interest of Juan-Carlos, including mechanics (particles, rigid bodies, fluids, elasticity, plastic ity, etc.), geometry, applied dynamics, and, of course, computation. His interests were extremely broad-he did not see boundaries between computation, mathematics, me chanics, and dynamics, and, in that sense, he ideally reflected the spirit of the journal and many of the most exciting areas of current scientific interest. Juan-Carlos was one of those select and gifted people who could cross interdisci plinary boundaries with extremely high quality and productive interactions of lasting value. His contributions, ranging from concrete engineering problems to fundamental mathematical theorems in geometric mechanics, are remarkable. In current conferences as well as in scientific books and articles, and over a wide range of subjects, one frequently hears how his ideas as well as specific results are often used and quoted-this is one indication of just how profound and fundamental his work has impacted the community.

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 Synopsis Structure-preserving Integrators in Nonlinear Structural Dynamics and Flexible Multibody Dynamics by : Peter Betsch
Download or read book Structure-preserving Integrators in Nonlinear Structural Dynamics and Flexible Multibody Dynamics written by Peter Betsch and published by Springer. This book was released on 2016-05-10 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on structure-preserving numerical methods for flexible multibody dynamics, including nonlinear elastodynamics and geometrically exact models for beams and shells. It also deals with the newly emerging class of variational integrators as well as Lie-group integrators. It discusses two alternative approaches to the discretization in space of nonlinear beams and shells. Firstly, geometrically exact formulations, which are typically used in the finite element community and, secondly, the absolute nodal coordinate formulation, which is popular in the multibody dynamics community. Concerning the discretization in time, the energy-momentum method and its energy-decaying variants are discussed. It also addresses a number of issues that have arisen in the wake of the structure-preserving discretization in space. Among them are the parameterization of finite rotations, the incorporation of algebraic constraints and the computer implementation of the various numerical methods. The practical application of structure-preserving methods is illustrated by a number of examples dealing with, among others, nonlinear beams and shells, large deformation problems, long-term simulations and coupled thermo-mechanical multibody systems. In addition it links novel time integration methods to frequently used methods in industrial multibody system simulation.
Book Synopsis Dynamics of Geometrically Nonlinear Sliding Beams by : Kamran Behdinan
Download or read book Dynamics of Geometrically Nonlinear Sliding Beams written by Kamran Behdinan and published by . This book was released on 1996 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The elasto-dynamics of flexible frame structures is of interest in many areas of engineering. In certain structural systems the deflections can be large enough to warrant a nonlinear analysis. For example, offshore structures, long suspension bridges and other relatively slender structures used in space applications require a geometrically nonlinear analysis. In addition, if the structure has deployable elements, as in some space structures, the required analysis becomes even more complex. Typical examples are spacecraft antennae, radio telescopes, solar panels and space-based manipulators with deployable elements. The main objective of the present work is to formulate the problem of sliding beams undergoing large rotations and small strains. Further we aim to develop efficient finite element technique for analysis of such complex systems. Finally we wish to examine the nature of the motion of sliding beams and point out its salient features. We start with two well known approaches in the nonlinear finite element static analysis of highly flexible structures, namely, the updated Lagrangian and the consistent co-rotational methods and extend these techniques to dynamic analysis of geometrically nonlinear beam structures. We analyse several examples by the same methods and compare the performance of each for efficiency and accuracy. Next, using McIver's extension of Hamilton's principle, we formulate the problem of geometrically flexible sliding beams by two different approaches. In the first the beam slides through a fixed rigid channel with a prescribed sliding motion. In this formulation which we refer to as the sliding beam formulation, the material points on the beam slide relative to a fixed channel. In the second formulation the material points on the fixed beam are observed by a moving observer on a sliding channel and the beam is axially at rest. The governing equations of motion for the two formulations describe the same physical problem and by mapping both to a fixed domain, using proper transformations, we show that the two sets of governing equations become identical. It is not, possible to find analytical solutions to our problem and we choose the Galerkin numerical method to obtain the transient response of the problem for the special case axially rigid beam. Next we follow a more elegant approach wherein we use the developed incremental nonlinear finite element approaches (the updated Lagrangian and the consistent co-rotational method) in conjunction with a variable time domain beam finite elements (where the number of elements is fixed and as mass enters the domain of interest, but the sizes of elements change in a prescribed manner in the undeformed configuration). To verify the formulation and its computational implementation we analyse many examples and compare our findings with those reported in the literature when possible. We also use these illustrative examples to identify the importance of various terms such as axial flexibility and foreshortening effects. Finally we look into the problem of parametric resonance for the beam with periodically varying length and we show that the regions of stability obtained in the literature, using a linear analysis, do not hold when a more realistic nonlinear analysis is undertaken.

This book was released on 2004 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: The recent developments in aerospace exploration have stimulated extensive research into the mechanics of large flexible space structures, such as dish antennas, space telescopes and solar collectors. Highly flexible structures are designed to undergo large displacements and rotations without plastic deformation. But when a structure undergoes large displacements, various secondary effects (e.g., rotary inertias, cross section warping) may become significant, and its statics and dynamics may involve several nonlinear effects, such as shortening effect, nonlinear curvatures, mid-plane stretching and modal couplings among vibration modes. Hence, nonlinear structural theories that can model large displacements and rotations are needed. Moreover, it is important to understand the nonlinear static and dynamic behaviors of highly flexible structures in order to design such structures. In this thesis we derive and use a geometrically exact beam theory to analyze large static deformations of beams, and perform numerical and experimental studies on the nonlinear dynamics of highly flexible beams. The multiple shooting method and the method of multiple scales were used to solve the nonlinear governing equations of a highly flexible cantilevered beam. A 3D motion analysis system is used to perform dynamic testing and to verify numerical results. Comparison of numerical and experimental results shows that the derived nonlinear beam theory can model very large displacements and rotations of beams.
