Описание: Although several books and conference proceedings have already appeared dealing with either the mathematical aspects or applications of homogenization theory, there seems to be no comprehensive volume dealing with both aspects. The present volume is meant to fill this gap, at least partially, and deals with recent developments in nonlinear homogenization emphasizing applications of current interest. It contains thirteen key lectures presented at the NATO Advanced Workshop on Nonlinear Homogenization and Its Applications to Composites, Polycrystals and Smart Materials. The list of thirty one contributed papers is also appended.The key lectures cover both fundamental, mathematical aspects of homogenization, including nonconvex and stochastic problems, as well as several applications in micromechanics, thin films, smart materials, and structural and topology optimization. One lecture deals with a topic important for nanomaterials: the passage from discrete to continuum problems by using nonlinear homogenization methods. Some papers reveal the role of parameterized or Young measures in description of microstructures and in optimal design. Other papers deal with recently developed methods вЂ“ both analytical and computational вЂ“ for estimating the effective behavior and field fluctuations in composites and polycrystals with nonlinear constitutive behavior. All in all, the volume offers a cross-section of current activity in nonlinear homogenization including a broad range of physical and engineering applications. The careful reader will be able to identify challenging open problems in this still evolving field. For instance, there is the need to improve bounding techniques for nonconvex problems, as well as for solving geometrically nonlinear optimum shape-design problems, using relaxation and homogenization methods.

Описание: According to the author and reviewers, more than 50% of the material taught in courses such as Advanced Dynamics, Mutibody Dynamics, and Spacecraft Dynamics is common to one another. Where graduate students in Mechanical and Aerospace Engineering may have the potential to work on projects that are related to any of the engineering disciplines, they have not been exposed to enough applications in both areas for them to use this information in the real world. The proposed book will bridge the gap between rigid body, multibody, and spacecraft dynamics for graduate students and specialists in mechanical and aerospace engineering. The engineers and graduate students who read this book will be able to apply their knowledge to a wide range of applications across different engineering disciplines. The book begins with a review on coordinate systems and particle dynamics which will teach coordinate frames. The transformation and rotation theory along with the differentiation theory in different coordinate frames will provides the required background to learn the rigid body dynamics based on Newton-Euler principles. Applications to this coverage can be found in vehicle dynamics, spacecraft dynamics, aircraft dynamics, robot dynamics, and multibody dynamics, each in a chapter. The Newton equations of motion will be transformed to Lagrange equation as a bridge to analytical dynamics. The methods of Lagrange and Hamilton will be applied on rigid body dynamics. Finally through the coverage of special applications this text provides understanding of advanced systems without restricting itself to a particular discipline. The author will provide a detailed solutions manual and powerpoint slides as ancillaries to this book.
Описание: LMT-Cachan is a joint laboratory Ecole Normale Superieure de Cachan, Pierre and Marie Curie University and the French Research Council CNRS. The Year 2000 marked the 25th anniversary of LMT. On this occasion, series of lectures was organized in Cachan in September-October, 2000. This publication contains the proceedings of these lectures.
Описание: This book provides a modern investigation into the bifurcation phenomena of physical and engineering problems. Systematic methods--based on asymptotic, probabilistic, and group-theoretic standpoints--are used to examine experimental and computational data from numerous examples (e.g., soil, sand, kaolin, concrete, domes, etc.). Engineers may find this book, with its minimized mathematical formalism, to be a useful introduction to modern bifurcation theory. For mathematicians, static bifurcation theory for finite dimensional systems, as well as its implications for practical problems, is illuminated by the numerous examples.
Описание: The ICPMSE-6 meeting continued the discussions started in 1992 when this conference series was started. The proceedings of ICPMSE-6 conference contain the latest developments in the area of the effects of the space environment on materials and structures and the ways to prevent and/or reduce them. For the first time, information on environment factors affecting the behavior of materials in GEO and MEO orbits was included in the topics. The main mandate of the meeting, as in the past years was to: - promote the dissemination of experimental data and experience among research organizations, and scientists gathered in ground and flight experiments; - learn about the latest advances in the field of material's and structures' protection in space environment and to provide a basis for interaction and utilization of ideas; - review the latest research and development in topics such as: effects of space environment on materials and structures, predictive models for interaction of materials with space environment factors, and alternative ways for protection from space environment.

Описание: This book is primarily a textbook written for engineers, students and teachers, and for people working on fatigue problems of engineering structures and materials. The book can be used for graduate and undergraduate courses, workshops, and short courses for people working in the industry or research institutes. The book also offers useful comments for researchers in view of the practical relevance of investigations and to plan future research. An important theme of the book is the understanding of what happens in the material of an engineering structure subjected to a spectrum of cyclic loads in service. Knowledge of the fatigue mechanism in the material and how it can be affected by a large variety of practical conditions is essential for dealing with fatigue problems. The structure must be designed for durability, and thus against fatigue. This includes not only the overall concept of the structure and safety and economic aspects, but also questions on detail design, joints, production and material surface quality. The designer must predict the fatigue performance of the structure. Knowledge of the various influencing factors is essential. Similar considerations arise if fatigue problems occur after a period in service when decisions have to be made on remedial actions. A unique feature of the book is the integrated approach to fatigue of engineering structures as outlined in the picture on the front cover of the book.
Описание: Adaptronic structures and systems can adapt automatically to variable operating and environmental conditions through the use of feedback control. But in contrast to conventional control loops, in which each function is fulfilled by a separate component, adaptronics is characterized by multifunctional components that are preferably integrated into the structure or the system. The goal is a lightweight and simple construction for conserving material and energy resources. The authors of this book have taken on the task of displaying the current state of the art in this highly modern and strongly interdisciplinary field. Selected application examples are also presented and current development trends demonstrated.

Описание: This book, intended for people in engineering and fundamental sciences, presents an integrated mathematical methodology for advanced dynamics and control of structures and machines, ranging from the derivation of models up to the control synthesis problem. This point of view is particularly useful as the physical insight and the associated structural properties, related e.g. to the Lagrangian or Hamiltonian framework, can be advantageously utilized. To this end, up to date results in disciplines like continuum mechanics, analytical mechanics, thermodynamics and electrodynamics are presented exploiting the differential geometric properties, with the basic notions of this coordinate-free approach revisited in an own chapter. In order to illustrate the proposed methodologies, several industrial applications, e.g., the derivation of exact solutions for the deformation compensation by shaped actuation in elastic bodies, or the coordination of rigid and flexible joint robots, are discussed.
