The Symposium opened with a keynote address entitled "Role of surface-anchored polymer chains in polymer friction" which described the processes taking place at the interface between "solid" and "liquid". The keynote address was followed by two invited lectures. Firstly, "Fuel efficient engine oils, additive interactions, boundary friction and wear" presented the industrial point of view on lubricant formulation and engine testing and its evolution. The second lecture was entitled "For establishment of a new EHL theory" and stressed the need to extend the current EHL theory.
Beginning in 1974, The Leeds-Lyon Symposia have now covered a wide range of topics. The essential aim each year is to select a topic of current interest to tribologists and to contribute to further the advance of knowledge in selected fields.
This volume gives a detailed and current review on some basic features of tribology particularly associated with internal combustion engines such as: lubrication analysis relevant to plain bearings, Hertzian contact theory and elastohydrodynamic lubrication associated with cams and followers and friction and wear in a general context. Several chapters examine engine bearings, valve trains, (cams and followers) and piston assemblies. For each machine element a background introduction is followed by design interpretations and a consideration of future developments. The important topic of materials, solids and lubricants is focused upon in the concluding chapters.
The work will be of interest to engineers and researchers in the automobile, automotive products, petroleum and associated industries.
There have been many advances in the field of tribology in recent years, with progress being made in the engineering and interaction of surfaces; micro and nano-tribology; elastohydrodynamics; surface films; surface texture; tribochemistry; wear and life prediction; with both experimental and theoretical contributions. These advances were reviewed, and the impact of this understanding on the fundamentals upon total engineering activity in design, manufacture and machine operation were considered.
Scientists and researchers in the field of tribology.
The Leeds-Lyon Symposia on Tribology were launched in 1974, and the large number of references to original work published in the Proceedings over many years confirms the quality of the published papers. It also indicates that the volumes have served their purpose and become a recognised feature of the tribological literature.
This year's title is 'Thinning Films and Tribological Interfaces', and the papers cover practical applications of tribological solutions in a wide range of situations.
The evolution of a full peer review process has been evident for a number of years. An important feature of the Leeds-Lyon Symposia is the presentation of current research findings. This remains an essential feature of the meetings, but for the 26th Symposium authors were invited to submit their papers for review a few weeks in advance of the Symposium. This provided an opportunity to discuss recommendations for modifications with the authors.
The approach adopted for defining design follows that developed by the SEED (Sharing Experience in Engineering Design) programme where design is viewed as "the total activity necessary to provide a product or process to meet a market need." Within this framework the book concentrates on developing detailed mechanical design skills in the areas of bearings, shafts, gears, seals, belt and chain drives, clutches and brakes, springs and fasteners. Where standard components are available from manufacturers, the steps necessary for their specification and selection are developed.
The framework used within the text has been to provide descriptive and illustrative information to introduce principles and individual components and to expose the reader to the detailed methods and calculations necessary to specify and design or select a component. To provide the reader with sufficient information to develop the necessary skills to repeat calculations and selection processes, detailed examples and worked solutions are supplied throughout the text.
This book is principally a Year/Level 1 and 2 undergraduate text. Pre-requisite skills include some year one undergraduate mathematics, fluid mechanics and heat transfer, principles of materials, statics and dynamics. However, as the subjects are introduced in a descriptive and illustrative format and as full worked solutions are provided, it is possible for readers without this formal level of education to benefit from this book. The text is specifically aimed at automotive and mechanical engineering degree programmes and would be of value for modules in design, mechanical engineering design, design and manufacture, design studies, automotive power-train and transmission and tribology, as well as modules and project work incorporating a design element requiring knowledge about any of the content described.
The aims and objectives described are achieved by a short introductory chapters on total design, mechanical engineering and machine elements followed by ten chapters on machine elements covering: bearings, shafts, gears, seals, chain and belt drives, clutches and brakes, springs, fasteners and miscellaneous mechanisms. Chapters 14 and 15 introduce casings and enclosures and sensors and actuators, key features of most forms of mechanical technology. The subject of tolerancing from a component to a process level is introduced in Chapter 16. The last chapter serves to present an integrated design using the detailed design aspects covered within the book. The design methods where appropriate are developed to national and international standards (e.g. ANSI, ASME, AGMA, BSI, DIN, ISO).
The first edition of this text introduced a variety of machine elements as building blocks with which design of mechanical devices can be undertaken. The approach adopted of introducing and explaining the aspects of technology by means of text, photographs, diagrams and step-by-step procedures has been maintained. A number of important machine elements have been included in the new edition, fasteners, springs, sensors and actuators. They are included here. Chapters on total design, the scope of mechanical engineering and machine elements have been completely revised and updated. New chapters are included on casings and enclosures and miscellaneous mechanisms and the final chapter has been rewritten to provide an integrated approach. Multiple worked examples and completed solutions are included.
This year's theme, Advances in Mechanical Behaviour, Plasticity and Damage, was proposed by the Societe Francaise de Metallurgie et de Materiaux (SF2M) to FEMS.
This publication contains a selection of papers presented at the EUROMAT 2000 Conference, held in Tours, France on 7-9 November 2000. The aim of this Conference was to concentrate mainly on recent advances made in the investigation of the relationship between microstructures of materials and their mechanical behaviour; including, fundamentals, modelling and applications. Encompassed in the Conference's aim is the nurturing of the synergistic effect between the theoretical and applied areas in this field. This was achieved by addressing important basic and practical aspects of the mechanical behaviour and damage of materials whilst also providing significant links between various complementary approaches.
All kinds of materials are covered and topics that were covered include the mechanics of solid polymers, microstructurs and micromechanisms, and the collective behavior of defects which looks at the interaction of multiple defects in a system.
The 66 papers in this volume provide reviews across the tribological field with thin films as their theme, giving a comprehensive and concise description on topics ranging from coatings and surface modification to bio-tribology. The articles provide the reader with an outline of their most effective application and potential uses in new technologies. The volume will be of interest not only to research workers and design engineers in the fields of new machine developments and lubrication, but also to engineers and students specialising in tribology.
The papers are organized into 13 sessions. The first two papers examine the use of ferrography in the analysis of non-ferrous particles as well as some of the methods of obtaining approximate numerical solutions to boundary-value problems that arise in elastohydrodynamic lubrication. The next session is concerned with rheology and contains papers that describe numerical solutions for power law fluids as applied to slider bearings; grease lubricated finite length bearings; and the use of the ball bearing as rheological test device. The papers that follow discuss bearings and their dynamics, oil films on lubricated surfaces, hydrodynamic lubrication, and finite element analysis of transient elastohydrodynamic lubrication. The final session considers plastic deformation, two body abrasion processes, and micropitting and asperity deformation.
This monograph will appeal to tribologists.
The symposium was attended by 87 delegates from 13 countries, which showed a great level of interest on the scientific and industrial problems of running-in. Twenty eight papers are presented in the book, covering basic thermodynamics, mechanics of continuous solids, metallurgy, polymers, profilometry, and surface physics. Major topics such as elastohydrodynamics, roughness, and thermal effects in tribology are discussed as well.
Mechanical engineers and materials scientists will find the book very insightful.
These proceedings contain more than seventy papers, written by authors from all over the world, covering the entire spectrum of fluid film lubrication. Of particular interest is the detailed consideration of a wide range of machine elements - bearings, seals, cams, rolling elements, as well as the in-depth, state-of-the-art, analytical contributions.
The contents include papers on the impact of automotive technology and environmental factors upon lubricant requirements, elasto-hydrodynamic lubrication, boundary lubrication, machine elements, bio-tribology, metal forming, rheology, lubricated wear and very thin film (nano metre) lubrication. Presented by leading scientists from 22 different countries, these proceedings provide an up-to-date review of developments in this field.
This book emphasizes advances in the working principals of the tribological components that operate with relative motion. The topics discussed include the dynamic analysis of engine bearing systems, measurement of oil film thickness in diesel motor main bearings, and temperature variations in crankshaft bearings. The theoretical and experimental study of ring-liner friction, tribology in the cylinders of reciprocating compressors, and lubricant properties in the diesel engine piston ring zone are also described. This text likewise considers the metallurgy of scoring and scuffing failure, impact of oil contamination on wear and energy losses, and role of tappet surface morphology and metallurgy in cam/tappet life.
This compilation is a good reference for triblogists, lubrication engineers, and specialists researching on reciprocating engines.
Comprised of 13 chapters, this volume begins with an overview of elasto-hydrodynamic lubrication and representation of contacts by cylinders, followed by a discussion on equations relevant to lubrication, including the Reynolds equation. The reader is then introduced to lubrication of rigid cylinders; the importance of film thickness in highly loaded rigid contacts; the elasticity of solids in contact; and the theory of elasto-hydrodynamic lubrication. Subsequent chapters focus on apparatus and measurements of film thickness and film shape; friction and viscosity; and lubrication of gears and roller bearings.
This book will be of interest to tribologists.

We will soon be able to meet and exceed the basic needs of every man, woman and child on the planet. Abundance for all is within our grasp. This bold, contrarian view, backed up by exhaustive research, introduces our near-term future, where exponentially growing technologies and three other powerful forces are conspiring to better the lives of billions. An antidote to pessimism by tech entrepreneur turned philanthropist, Peter H. Diamandis and award-winning science writer Steven Kotler.
Since the dawn of humanity, a privileged few have lived in stark contrast to the hardscrabble majority. Conventional wisdom says this gap cannot be closed. But it is closing—fast. The authors document how four forces—exponential technologies, the DIY innovator, the Technophilanthropist, and the Rising Billion—are conspiring to solve our biggest problems. Abundance establishes hard targets for change and lays out a strategic roadmap for governments, industry and entrepreneurs, giving us plenty of reason for optimism.
Examining human need by category—water, food, energy, healthcare, education, freedom—Diamandis and Kotler introduce dozens of innovators making great strides in each area: Larry Page, Steven Hawking, Dean Kamen, Daniel Kahneman, Elon Musk, Bill Joy, Stewart Brand, Jeff Skoll, Ray Kurzweil, Ratan Tata, Craig Venter, among many, many others.
A radical, how-to guide for using exponential technologies, moonshot thinking, and crowd-powered tools, Bold unfolds in three parts. Part One focuses on the exponential technologies that are disrupting today’s Fortune 500 companies and enabling upstart entrepreneurs to go from “I’ve got an idea” to “I run a billion-dollar company” far faster than ever before. The authors provide exceptional insight into the power of 3D printing, artificial intelligence, robotics, networks and sensors, and synthetic biology. Part Two draws on insights from billionaires such as Larry Page, Elon Musk, Richard Branson, and Jeff Bezos and reveals their entrepreneurial secrets. Finally, Bold closes with a look at the best practices that allow anyone to leverage today’s hyper-connected crowd like never before. Here, the authors teach how to design and use incentive competitions, launch million-dollar crowdfunding campaigns to tap into tens of billions of dollars of capital, and finally how to build communities—armies of exponentially enabled individuals willing and able to help today’s entrepreneurs make their boldest dreams come true.
Containing nearly 3,000 references, tables, equations, figures, drawings, and photographs, the book provides practical examples encompassing everything from electronic circuits to high power circuits, or microamperes to mega amperes. The new edition:

The manufacturers of machinery give guidelines on the operation, lubrication and maintenance required for their particular equipment. There are however many different machines in an industrial plant or service organisation, often supplied by many different manufacturers, and there is a need to select as many similar lubricants as possible and to use related machine techniques. This book bridges the gap which exists between the available data on the various machines by providing overall guidance on how to co-ordinate the recommendations of the various equipment makers.
The book is structured in a number of sections that will make it easier to use, and to bring together related topics so that when a reader is focusing on a particular problem they can also refer to related material that is also likely to be of interest.

First invented in 1947, hydraulic fracturing, or fracking, has not only become a major source of energy, it is changing the way we use energy, and the energy we use. It is both a threat and a godsend for the environment, and it is leading the revival of manufacturing in the United States.
A definitive narrative history, The Boom follows the twists and turns in the development and adoption of this radical technology. It is a thrilling journey filled with colorful characters: the green-minded Texas oilman who created the first modern frack; a bare-knuckled Oklahoman natural gas empire-builder who gave the world an enormous new supply of energy and was brought down by his own success and excesses; an environmental leader whose embrace of fracking brought an end to his public career; and an aging fracking pioneer who is now trying to save the industry from itself.
A fascinating and exciting exploration of one of the most controversial and promising sources of energy, The Boom “brings new clarity to a subject awash in hype from all sides…a thoughtful, well-written, and carefully researched book that provides the best overview yet of the pros and cons of fracking. Gold quietly leads both supporters and critics of drilling to consider other views” (Associated Press).
This operation always presents the challenge of selecting a cutting tool insert that facilitates an extended tool life and high-precision machining of the component. Hard machining presents several advantages when compared with the traditional methodology based on finish grinding operations after heat treatment of workpieces. This technology also offers a great contribution to sustainable manufacturing.
Hard materials comprise hardened steels, high-speed steels, heat-treatable steels, tool steels, bearing steels and chilled/white cast irons. Inconnel, Hastelloy, cobalt alloys for biomedical applications and other special materials are also classified as hard materials. These materials are in constant use by the automotive industry for bearing production and for the machining of dies and moulds as well as other components for advanced industries.
Machining of Hard Materials aims to provide the fundamentals and recent advances in the study of hard machining of materials. All chapters are written by international experts in this important field of research.
Chapter 1 defines machining of hard materials and its application in industry. Chapter 2 is dedicated to advanced cutting tools used for the machining of hard materials. Chapter 3 describes the mechanics of the cutting and chip formation. Chapter 4 contains information on surface integrity. Chapter 5 is dedicated to finite element modelling and simulation. Finally, Chapter 6 is dedicated to computational methods and optimization.
Machining of Hard Materials can serve as a useful reference for academics; manufacturing and materials researchers; manufacturing and mechanical engineers; and professionals in machining and related industries.
The Conundrum is a mind-changing manifesto about the environment, efficiency and the real path to sustainability.
Hybrid cars, fast trains, compact florescent light bulbs, solar panels, carbon offsets: Everything you've been told about living green is wrong. The quest for a breakthrough battery or a 100 mpg car are dangerous fantasies. We are consumers, and we like to consume green and efficiently. But David Owen argues that our best intentions are still at cross purposes to our true goal - living sustainably and caring for our environment and the future of the planet. Efficiency, once considered the holy grail of our environmental problems, turns out to be part of the problem. Efforts to improve efficiency and increase sustainable development only exacerbate the problems they are meant to solve, more than negating the environmental gains. We have little trouble turning increases in efficiency into increases in consumption.
David Owen's The Conundrum is an elegant nonfiction narrative filled with fascinating information and anecdotes takes you through the history of energy and the quest for efficiency. This is a book about the environment that will change how you look at the world. We should not be waiting for some geniuses to invent our way out of the energy and economic crisis we're in. We already have the technology and knowledge we need to live sustainably. But will we do it?
That is the conundrum.
From the Trade Paperback edition.
According to Stewart Brand, a lifelong environmentalist who sees everything in terms of solvable design problems, three profound transformations are under way on Earth right now. Climate change is real and is pushing us toward managing the planet as a whole. Urbanization?half the world?s population now lives in cities, and eighty percent will by midcentury?is altering humanity?s land impact and wealth. And biotechnology is becoming the world?s dominant engineering tool. In light of these changes, Brand suggests that environmentalists are going to have to reverse some longheld opinions and embrace tools that they have traditionally distrusted. Only a radical rethinking of traditional green pieties will allow us to forestall the cataclysmic deterioration of the earth?s resources.
Whole Earth Discipline shatters a number of myths and presents counterintuitive observations on why cities are actually greener than countryside, how nuclear power is the future of energy, and why genetic engineering is the key to crop and land management. With a combination of scientific rigor and passionate advocacy, Brand shows us exactly where the sources of our dilemmas lie and offers a bold and inventive set of policies and solutions for creating a more sustainable society.
In the end, says Brand, the environmental movement must become newly responsive to fast-moving science and take up the tools and discipline of engineering. We have to learn how to manage the planet?s global-scale natural infrastructure with as light a touch as possible and as much intervention as necessary.
