Part of a series of core databooks within the William Andrew Plastics Design Library, Fatigue and Tribological Properties of Plastics and Elastomers provides a comprehensive collection of graphical multipoint data and tabular data covering fatigue and tribology. The concept of fatigue is very straightforward: if an object is subjected to a stress or deformation, and it is repeated, the object becomes weaker. This weakening of plastic material is called fatigue. Tribology is the science and technology of surfaces in contact with each other and therefore covers friction, lubrication and wear. The reduction of wear and fatigue and the improvement of lubrication are key bottom-line issues for engineers and scientists involved in the plastics industry and product design with plastics. Fatigue and Tribological Properties of Plastics and Elastomers, 2e, is an update of all that has changed in the world of plastics since the 1st edition appeared nearly 15 years ago, and has been reorganized from a polymer chemistry point of view. A hard-working reference tool: part of the daily workflow of engineers and scientists involved in the plastics industry and product design with plastics The reduction of wear and fatigue and the improvement of lubrication are key bottom-line issues The data in this book provide engineers with the tools they need to design for low failure rates

Readers of this book will become familiar with the concepts and techniques of nanotribology, explained by an international team of scientists and engineers, actively involved and with long experience in this field. Edited by two pioneers in the field, the book is suitable both as a first introduction to this fascinating subject, and also as a reference for researchers wishing to improve their knowledge of nanotribology.
This application-oriented book introduces readers to the associations and relationships between contact mechanics and friction, providing them with a deeper understanding of tribology. It addresses the related phenomena of contacts, adhesion, capillary forces, friction, lubrication, and wear from a consistent point of view. The author presents (1) methods for rough estimates of tribological quantities, (2) simple and general methods for analytical calculations, and (3) the crossover into numerical simulation methods, the goal being to convey a consistent view of tribological processes at various scales of magnitude (from nanotribology to earthquake research). The book also explores the system dynamic aspects of tribological systems, such as squeal and its suppression, as well as other types of instabilities and spatial patterns. It includes problems and worked-out solutions for the respective chapters, giving readers ample opportunity to apply the theory to practical situations and to deepen their understanding of the material discussed. The second edition has been extended with a more detailed exposition of elastohydrodynamic lubrication, an updated chapter on numerical simulation methods in contact mechanics, a new section on fretting in the chapter on wear, as well as numerous new exercises and examples, which help to make the book an excellent reference guide.

Polymers and polymer composites have been increasinqly used in place of metals for various industries; namely, aerospace, automotive, bio-medical, computer, electrophotography, fiber, and rubber tire. Thus, an understanding of the interactions between polymers and between a polymer and a rigid counterface can enhance the applications of polymers under various environments. In meet ing this need, polymer tribology has evolved to deal with friction, lubrication and wear of polymeric materials and to answer some of the problems related to polymer-polymer interactions or oolymer rigid body interactions. The purpose of this first International Symposium was to introduce advances in studies of polymer friction and wear, especially in Britain and the U.S.S.R. Most earlier studies of the Fifties were stimulated by the growth of rubber tire industries. Continuous research through the Sixties has broadened the base to include other polymers such as nylon, polyolefins, and poly tetra fluoroethylene, or PTFE. However, much of this work was published in engineering or physics journals and rarely in chemistry journals; presumably, the latter have always considered the work to be too applied or too irrelevant. Not until recent years have chemists started to discover words such as tribo-chemistry or mechano chemistry and gradually become aware of an indispensable role in this field of polymer tribology. Thus, we were hoping to bring the technology up to date during this SympOSium, especially to the majority of participants, polymer chemists by training.
Friction, wear, and erosion are major issues in mechanical engineering and materials science, resulting in major costs to businesses operating in the automotive, biomedical, petroleum/oil/gas, and structural engineering industries. The good news is, by understanding what friction, wear, or erosion mode predominates in a mechanism or device, you can take action to prevent its costly failure. Seeing Is Believing Containing nearly 300 photos of component failures, macro- and micrographs of surface damage, and schematics on material removal mechanisms collected over 50 years of tribology consulting and research, Friction, Wear, and Erosion Atlas is a must-have quick reference for tribology professionals and laymen alike. Complete with detailed explanations of every friction, wear, and erosion process, the atlas’ catalog of images is supported by a wealth of practical guidance on: Diagnosing the specific causes of part failure Identifying popular modes of wear, including rolling and impact, with a special emphasis on adhesion and abrasion Understanding manifestations of friction, such as force traces from a laboratory test rig for a variety of test couples Recognizing liquid droplet, solid particle, slurry, equal impingement, and cavitation modes of erosion Developing solutions to process-limiting problems Featuring a glossary of tribology terms and definitions, as well as hundreds of visual representations, Friction, Wear, and Erosion Atlas is both user friendly and useful. It not only raises awareness of the importance of tribology, but provides guidance for how designers can proactively mitigate tribology concerns.
This book provides an updated review on the development of scanning probe microscopy and related techniques, and the availability of computational techniques not even imaginable a few decades ago. The 36 chapters cover instrumental aspects, theoretical models and selected experimental results, thus offering a broad panoramic view on fundamental issues in nanotribology which are currently being investigated. Compared to the first edition, several topics have been added, including triboluminescence, graphene mechanics, friction and wear in liquid environments, capillary condensation, and multiscale friction modeling. Particular care has been taken to avoid overlaps and guarantee the independence of the chapters. In this way, our book aims to become a key reference on this subject for the next five to ten years to come.

Providing a useful summary of current knowledge on the friction and wear properties of composite materials, this book fills the gap between publications on fundamental principles of tribology and those on the friction and wear behavior of metals and polymers. Detailed coverage is given of: the fundamental aspects of tribology in general and polymer composites in particular; the effects of the microstructure of composites on friction and wear behavior under different external loading conditions; and the problem of the control of friction and wear behavior in practical situations. Although emphasis is on polymer composites associated with bearing-type applications, part of the book is also devoted to the friction and wear of metal-based composites and rubber compounds. The data are represented in the form of 277 figures, diagrams and photographs, and 68 tables. The author index covers more than 670 references, and the subject index more than 1,000 keywords. The book will be of particular interest to: those involved in research on some aspects of polymer composites tribology (material scientists, physical chemists, mechanical engineers); those wishing to learn more methods for solving practical friction or wear problems (designers, engineers and technologists in industries, dealing with selection, reprocessing and application of polymer engineering materials); and teachers and students at universities.
