Tribology in Environmental Design is an indispensable collection of chapters exploring the life cycle of all stages of tribological issues for product design. The contributors for this edition are from a wide range of disciplines and countries ensuring a comprehensive overview of Tribology in Environment Design. This well-renowned second international conference explores the role of tribology in the context of product design and how this influences environmental, as well as product life cycle, consequences. Topics covered include: Sustainable Design Life-oriented Products Life-cycle Assessment for Optimized Products Surface Engineering Lubricants Test Methods Advanced Materials Analytical Studies

The 31st Leeds-Lyon Symposium on Tribology was held at Trinity and All Saints College in Leeds under the title "Life Cycle Tribology" from Tuesday 7th September until Friday 10th September 2004. Over the three days of presentations that followed, life cycle tribology was explored across a range of areas including automotive tribology, bearings, bio-degradability and sustainability, bio-tribology, coatings, condition monitoring, contact mechanics, debris effects, elastohydrodynamic lubrication, lubricants, machine systems, nanotribology, rolling contact fatigue, transmissions, tribochemistry and wear and failure. Invited talks in these fields were presented by leading international researchers and practitioners, namely C.J. Hooke, J.A. Williams, R.J.K. Wood, G. Isaac, S.C. Tung, D. Price, I. Sherrington, M. Hadfield, K. Kato, R.I. Taylor, H.P. Evans, R.S. Dwyer-Joyce and H. Rahnejat.

The increasing demand for energy, raw materials and goods arising from world population growth, the emerging concept of sustainable development is concerned with meeting such challenges. The widely accepted Brundtland definition of sustainable development states that it is the ability to meet the needs of the present without compromising the ability of future generations to meet their own needs. The papers in this volume are from a conference organised by the University of Liverpool in September 2003 and are dedicated to the holistic study and interchange of ideas on the theory, technology, tools, methodology for the entire product life cycle within the framework of sustainable development. Design and Manufacture for Sustainable Development 2003 brings together industry leaders and the cutting edge of academic research in this critical area and includes, Life cycle engineering - from methodology to enterprise culture teaching mechanical engineering course relating to the environment Biodegradable plastics for hygenic disposable products Assessment for product sustainability An exploration of the role values play in designer decision making and how this effects ecodesign outcomes Laser technology applied to sustainable demolition and high-energy, re-usable bricks Sustainability principles for product design Public perceptions of sustainability, energy efficiency and recycling - how these can inform the design process

Surface science and tribology play very critical roles in many industries. Manufacture and use of almost all consumer and industrial products rely on the application of advanced surface and tribological knowledge. The fourth in a series, Surfactants in Tribology, Volume 4 provides an update on research and development activities connecting surfactants and tribological phenomena. Written by renowned subject matter experts, the book demonstrates how improved design of surfactants can be harnessed to control tribological phenomena. Profusely illustrated and copiously referenced, the chapters also discuss novel approaches to control tribological phenomena using surfactants including green surfactants. It also discusses the underlying tribological and surface science issues relevant to many situations in diverse industries. The information in this volume provides a cutting-edge reference connecting the fields of surfactants and tribology as a way forward to novel, enhanced methods of controlling lubrication, friction, and wear. It reflects the latest developments, highlighting the relevance of surfactants in tribological phenomena in a broad range of industries. As we learn more about the connection between surfactants and tribology, new and improved ways to control lubrication, friction, and wear utilizing surfactants will emerge. This book takes us farther on the path towards this goal.

In order to meet the challenges of sustainable production, industries have more responsibility in controlling product-related environmental aspects throughout the whole life cycle of a product, since industrial products have potentially larger impacts than on-site emissions. This book looks at Ecodesign as a special form of product management, integratable into Total Live Cycle Management.

This volume describes the application of the method of the differential specific forces (MDSF). By using this new method, the solutions to the problems of a dissipative viscoelastic and elastic-plastic contacts between curvilinear surfaces of two solid bodies can be found. The novelty is that the forces of viscosity and the forces of elasticity can be found by an integration of the differential specific forces acting inside an elementary volume of the contact zone. This volume shows that this method allows finding the viscoelastic forces for any theoretical or experimental dependencies between the distance of mutual approach of two curvilinear surfaces and the radiuses of the contact area. Also, the derivation of the integral equations of the viscoelastic forces has been given and the equations for the contact pressure have been obtained. The viscoelastic and elastic-plastic contacts at impact between two spherical bodies have been examined. The equations for work and energy in the phases of compression and restitution and at the rolling shear have been obtained. Approximate solutions for the differential equations of movement (displacement) by using the method of equivalent work have been calculated. This new method of differential specific viscoelastic forces allows us to find the equations for all viscoelastic forces. It is principally different from other methods that use Hertz’s theory, the classical theory of elasticity and the tensor algebra. This method will be useful in research of contact dynamics of any shape of contacting surfaces. It also can be used for determination of the dynamic mechanical properties of materials and in the design of wear-resistant elements and coverings for components of machines and equipment that are in harsh conditions where they are subjected to the action of flow or jet abrasive particles. This volume will be useful for professional designers of machines and mechanisms as well as for the design and development of new advanced materials, such as wear-resistant elastic coatings and elements for pneumatic and hydraulic systems, stop valves, fans, centrifugal pumps, injectors, valves, gate valves, and in other installations.
