Extensively revised and thoroughly updated, this popular text de-emphasizes high level mathematics in favor of effective, accurate modeling. Real-world examples amplify the theory and show how to use derived equations to model physical problems. Exercises that parallel the examples build readers' confidence and prepare them to confront the more complex situations they encounter as professionals.

Finite Element Analysis is a very popular, computer-based tool that uses a complex system of points called nodes to make a grid called a "mesh". The mesh contains the material and structural properties that define how the structure will react to certain loading conditions, allowing virtual testing and analysis of stresses or changes applied to the material or component design. This groundbreaking text extends the usefulness of finite element analysis by helping both beginners and advanced users alike. It simplifies, improves, and extends both the finite element method while at the same time advancing adaptive refinement procedures. The book presents: A more simplified approach to finite element analysis based on computational continuum mechanics Physically interpretable notation that identifies a common basis for the finite element and the finite difference methods New point-wise error estimators that identify errors in terms of quantities of direct interest in solid mechanics

The unique focus of the book is the close symbiotic relationship between design and manufacture. It covers a large number of actual issues in the field by authors from the main research groups involved in developing methods, models and tools for the improvement of design and manufacturing processes in companies. It presents a selection of thirty-three papers ensuing from the fifth International Conference on Integrated Design and Manufacturing in Mechanical Engineering, held at the University of Bath, UK, in April 2004.

The contributions are divided in the following sections: two keynotes presenting the general synergies and relationships between the design and manufacturing processes through the concepts of production knowledge and integration; design strategies and methodologies, dealing with the critical element of knowledge in design and manufacturing processes and the methods with which designing can be undertaken collaboratively in an integrated manner; integrated design of manufacturing processes, which aim is to ensure a high quality product meeting all requirements, rapidly and at optimum cost; and design tools for particular applications in which texts optimising local decision have been grouped.

The book is of interest to academics, students and practitioners specialising in design and manufacturing issues in mechanical engineering, who will find it of the greatest interest to compare various points of view within the fields broached throughout the Conference. This volume is recommended as a reference textbook for all researchers in this field. It will give teachning staff confronted with training methodologies in integrated design and production a toolto assess the scope of the development prospects in an extremely wide ranging field.

Direct injection spark-ignition engines are becoming increasingly important, and their potential is still to be fully exploited. Increased power and torque coupled with further reductions in fuel consumption and emissions will be the clear trend for future developments. From today's perspective, the key technologies driving this development will be new fuel injection and combustion processes. The book presents the latest developments, illustrates and evaluates engine concepts such as downsizing and describes the requirements that have to be met by materials and operating fluids. The outlook at the end of the book discusses whether future spark-ignition engines will achieve the same level as diesel engines.

The articles in this book present advanced soft methods related to genetic and evolutionary algorithms, immune systems, formulation of deterministic neural networks and Bayesian NN. Many attention is paid to hybrid systems for inverse analysis fusing soft methods and the finite element method. Numerical efficiency of these soft methods is illustrated on the analysis and design of complex engineering structures.

The Fifth International Symposium on Distributed Autonomous Robotic Systems (DARS 2000) dealt with new strategies to realize complex, modular, robust, and fault-tolerant robotic systems. Technologies, algorithms, and system architectures for distributed autonomous robotic systems were presented and discussed during the meeting. DARS 2000 was truly an international event, with participants represent ing eleven countries from Europe, Asia, and the Americas. All of the papers in this volume were presented at DARS 2000, and were selected on the basis of peer re views to ensure quality and relevance. These papers have the common goal of con tributing solutions to realize robust and intelligent multirobot systems. The topics of the symposium address a wide range of issues that are important in the development of decentralized robotic systems. These topics include architec tures, communication, biological inspirations, reconfigurable robots, localization, exploration and mapping, distributed sensing, multi robot motion coordination, tar get assignment and tracking, multirobot learning, and cooperative object transport. DARS clearly requires a broad area of interdisciplinary technologies related not only to robotics and computer engineering, but also to biology and psychology. The DARS symposium is the leading established conference on distributed au tonomous systems. The First, Second, and Third International Symposia on Distrib uted Autonomous Robotic Systems (DARS '92, DARS '94, and DARS '96) were held at the Institute of Physical and Chemical Research (RIKEN), Saitama, Japan."

The significant advances witnessed over the last years in the broad field of linguistic variation testify to a growing convergence between sociolinguistic approaches and the somewhat older historical and comparative research traditions. Particularly within cognitive and functional linguistics, the evolution towards a maximally dynamic approach to language goes hand in hand with a renewed interest in corpus research and quantitative methods of analysis. Many researchers feel that only in this way one can do justice to the complex interaction of forces and factors involved in linguistic variability, both synchronically and diachronically. The contributions to the present volume illustrate the ongoing evolution of the field. By bringing together a series of analyses that rely on extensive corpuses to shed light on sociolinguistic, historical, and comparative forms of variation, the volume highlights the interaction between these subfields. Most of the contributions go back to talks presented at the meeting of the Societas Linguistica Europaea held in Leuven in 2001. The volume starts with a global typological view on the sociolinguistic landscape of Europe offered by Peter Auer. It is followed by a methodological proposal for measuring phonetic similarity between dialects designed by Paul Heggarty, April McMahon, and Robert McMahon. Various papers deal with specific phenomena of socially and conceptually driven variation within a single language. For Dutch, Jose Tummers, Dirk Speelman, and Dirk Geeraerts analyze inflectional variation in Belgian and Netherlandic Dutch, Reinhild Vandekerckhove focuses on interdialectal convergence between West-Flemish urban dialects, and Arjan van Leuvensteijn studies competing forms of address in the 17th century Dutch standard variety. The cultural and conceptual dimension is also present in the diachronic lexicosemantic explorations presented by Heli Tissari, Clara Molina, and Caroline Gevaert for English expressions referring to the experiential domains of love, sorrow and anger, respectively: the history of words is systematically linked up with the images they convey and the evolving conceptualizations they reveal. The papers by Heide Wegener and by Marcin Kilarski and Grzegorz Krynicki constitute a plea against arbitrariness of alternations at the level of nominal morphology: dealing with marked plural forms in German, and with gender assignment to English loanwords in the Scandinavian languages, respectively, their distributional accounts bring into the picture a variety of motivating factors. The four cross-linguistic studies that close the volume focus on the differing ways in which even closely related languages exploit parallel morphosyntactic patterns. They share the same methodological concern for combining rigorous parametrization and quantification with conceptual and discourse-functional explanations. While Griet Beheydt and Katleen Van den Steen confront the use of formally defined competing constructions in two Germanic and two Romance languages, respectively, Torsten Leuschner as well as Gisela Harras and Kirsten Proost analyze how a particular speaker's attitude is expressed differently in various Germanic languages.

A systematic treatment of the thermal and elastic deformation of bearings, seals, and other machine elements under a wide variety of conditions, with particular emphasis on failure mechanisms when high speeds or loads cause significant frictional heating and on methods for predicting and avoiding such failures. Intended for designers and mechanical engineers responsible for high-performance machinery, the book is unique in discussing instabilities driven by frictional heating and thermal expansion and in developing a theoretical approach to engineering design in those cases in which the thermal problems are pivotal. It thus provides a guide as to what is important in the development of high-performance engineering systems. References to recent publications, new material that fill gaps in the literature, a consistent nomenclature, and a large number of worked examples make this a useful text and reference for both researchers and practising engineers.

It is our pleasure to present these proceedings for "The Aerodynamics of Heavy Vehicles II: Trucks, Buses and Trains" International Conference held in Lake - hoe, California, August 26-31, 2007 by Engineering Conferences International (ECI). Brought together were the world's leading scientists and engineers from industry, universities, and research laboratories, including truck and high-speed train manufacturers and operators. All were gathered to discuss computer simu- tion and experimental techniques to be applied for the design of the more efficient trucks, buses and high-speed trains required in future years. This was the second conference in the series. The focus of the first conference in 2002 was the interplay between computations and experiment in minimizing ae- dynamic drag. The present proceedings, from the 2007 conference, address the development and application of advanced aerodynamic simulation and experim- tal methods for state-of-the-art analysis and design, as well as the development of new ideas and trends holding promise for the coming 10-year time span. Also - cluded, are studies of heavy vehicle aerodynamic tractor and trailer add-on - vices, studies of schemes to delay undesirable flow separation, and studies of - derhood thermal management.

One of the next challenges in vehicular technology field is to improve drastically the road safety. Current developments are focusing on both vehicle platform and diverse assistance systems. This book presents a new engineering approach based on lean vehicle architecture ready for the drive-by-wire technology.

Based on a cognitive functionality split, execution and command levels are detailed. The execution level centralized over the stability control performs the motion vector coming from the command level. At this level the driver generates a motion vector which is continuously monitored by a virtual co-pilot. The integration of assistance systems in a safety relevant multi-agent system is presented here to provide first an adequate feedback to the driver to let him recover a dangerous situation. Robust strategies are also presented for the intervention phase once the command vehicle has to be optimized to stay within the safety envelope.

Micromechanisms of Fracture and Fatigue forms the culmination of 20 years of research in the field of fatigue and fracture. It discusses a range of topics and comments on the state of the art for each. The first part is devoted to models of deformation and fracture of perfect crystals. Using various atomistic methods, the theoretical strength of solids under simple and complex loading is calculated for a wide range of elements and compounds, and compared with experimental data. The connection between the onset of local plasticity in nanoindentation tests and the ideal shear strength is analysed using a multi-scale approach. Moreover, the nature of intrinsic brittleness or ductility of perfect crystal lattices is demonstrated by the coupling of atomistic and mesoscopic approaches, and compared with brittle/ductile behaviour of engineering materials. The second part addresses extrinsic sources of fracture toughness of engineering materials, related to their microstructure and microstructurally-induced crack tortuosity. Micromechanisms of ductile fracture are also described, in relation to the fracture strain of materials. Results of multilevel modelling, including statistical aspects of microstructure, are used to explain remarkable phenomena discovered in experiments. In the third part of the book, basic micromechanisms of fatigue cracks propagation under uniaxial and multiaxial loading are discussed on the basis of the unified mesoscopic model of crack tip shielding and closure, taking both microstructure and statistical effects into account. Applications to failure analysis are also outlined, and an attempt is made to distinguish intrinsic and extrinsic sources of materials resistance to fracture. Micromechanisms of Fracture and Fatigue provides scientists, researchers and postgraduate students with not only a deep insight into basic micromechanisms of fracture behaviour of materials, but also a number of engineering applications.

This book presents recent research into developing and applying computational tools to estimate the performance and safety of hydraulic structures from the planning and construction stage to the service period. Based on the results of a close collaboration between the author and his colleagues, friends, students and field engineers, it shows how to achieve a good correlation between numerical computation and the actual in situ behavior of hydraulic structures. The book's heuristic and visualized style disseminates the philosophy and road map as well as the findings of the research. The chapters reflect the various aspects of the three typical and practical methods (the finite element method, the block element method, the composite element method) that the author has been working on and made essential contributions to since the 1980s. This book is an advanced continuation of Hydraulic Structures by the same author, published by Springer in 2015.

There is a growing number of applications that require fast-rotating machines; motivation for this thesis comes from a project in which downsized spindles for micro-machining have been researched. The thesis focuses on analysis and design of high-speed PM machines and uses a practical design of a high-speed spindle drive as a test case. Phenomena, both mechanical and electromagnetic, that take precedence in high-speed permanent magnet machines are identified and systematized. The thesis identifies inherent speed limits of permanent magnet machines and correlates those limits with the basic parameters of the machines. The analytical expression of the limiting quantities does not only impose solid constraints on the machine design, but also creates the way for design optimization leading to the maximum mechanical and/or electromagnetic utilization of the machine. The models and electric-drive concepts developed in the thesis are evaluated in a practical setup.

This book expounds on progress made over the last 35 years in the theory, synthesis, and application of triboluminescence for creating smart structures. It presents in detail the research into utilization of the triboluminescent properties of certain crystals as new sensor systems for smart engineering structures, as well as triboluminescence-based sensor systems that have the potential to enable wireless, in-situ, real time and distributed (WIRD) structural health monitoring of composite structures. The sensor component of any structural health monitoring (SHM) technology - measures the effects of the external load/event and provides the necessary inputs for appropriate preventive/corrective action to be taken in a smart structure - sits at the heart of such a system. This volume explores advances in materials properties and structural behavior underlying creation of smart composite structures and sensor systems for structural health monitoring of critical engineering structures, such as bridges, aircrafts, and wind blades.

Heat exchangers are important, and used frequently in the processing, heat and power, air-conditioning and refrigeration, heat recovery, transportation and manufacturing industries. Such equipment is also important in electronics cooling and for environmental issues like thermal pollution, waste disposal and sustainable development. The present book concerns plate heat exchangers (PHEs), which are one of the most common types in practice. The overall objectives are to present comprehensive descriptions of such heat exchangers and their advantages and limitations, to provide in-depth thermal and hydraulic design theory for PHEs, and to present state-of-the-art knowledge.The book starts with a general introduction and historical background to PHEs, then discusses construction and operation (PHE types, plate pattern, etc.) and gives examples of PHEs in different application areas. Material issues (plates, gaskets, brazing materials) and manufacturing methods are also treated.The major part of the book concerns the basic design methods for both single-phase and two-phase flow cases, various flow arrangements, thermal-hydraulic performance in single-phase flow and for PHEs operating as condensers and evaporators. Fouling problems are also discussed and in a section on extended design and operation issues, modern Research and Development (R & D) tools like computational fluid dynamics (CFD) methods are discussed. Unique features for PHEs are discussed throughout.
