Improving our understanding of friction, lubrication, and fatigue, Modeling and Analytical Methods in Tribology presents a fresh approach to tribology that links advances in applied mathematics with fundamental problems in tribology related to contact elasticity, fracture mechanics, and fluid film lubrication. The authors incorporate the classical tenets of tribology while providing new mathematical solutions that address various shortcomings in existing theories. From contact interactions to contact fatigue life, the book connects traditionally separate areas of tribology research to create a coherent modeling methodology that encompasses asymptotic and numerical techniques. The authors often demonstrate the efficacy of the models by comparing predictions to experimental data. In most cases, they derive equations from first principles. They also rigorously prove problem formulations and derive certain solution properties. Solutions to problems are presented using simple analytical formulas, graphs, and tables. In addition, the end-of-chapter exercises highlight points important for comprehending the material and mastering the appropriate skills. Unlocking the secrets that govern the physics of lubricated and dry contacts, this book helps tribologists on their quest to reduce friction, minimize wear, and extend the operating life of mechanical equipment. It provides a real-world industrial perspective so that readers can attain a practical understanding of the material.

The argument over which values of oil viscosity best correlate with measures of engine operation has gone on for many years. Over a decade ago (1977), the membership of the Engine Oil Subcommittee of the Society of Automotive Engineers (SAE) Fuels and Lubricants Committee (now the Fuels and Lubricants Division) agreed that there were enough data to justify asking the appropriate ASTM subcommittee (D02.07) to develop methods for determining values of high-temperature, high-shear-rate (HTHS) oil viscosity and to relate them to engine operation. In 1984, an ASTM task force finished reviewing the available literature and composed a report that summarized the effects of viscosity on bearing oil film thickness, engine wear, engine friction, and fuel economy (ASTM DS-62). This paper reviews the findings of that report and updates them in light of recent studies. The case for incorporating HTHS viscosity specifications into the Engine Oil Viscosity Classification, SAE J300, is presently stronger than ever. Suggestions are offered on how this incorporation might be accomplished and on what future directions ASTM research on HTHS viscosity should take.

This handbook deals with the vast subject of thermal management of engines and vehicles by applying the state of the art research to diesel and natural gas engines. The contributions from global experts focus on management, generation, and retention of heat in after-treatment and exhaust systems for light-off of NOx, PM, and PN catalysts during cold start and city cycles as well as operation at ultralow temperatures. This book will be of great interest to those in academia and industry involved in the design and development of advanced diesel and CNG engines satisfying the current and future emission standards.
