Water-Lubricated Journal Bearings: Marine Applications, Design, and Operational Problems and Solutions provides cutting-edge design solutions, common problems and methods for avoiding them, and material selection considerations for the use of water-lubricated journal bearings in marine environments. These bearings have many advantages, including the absence of the potential for oil contamination. They are also sensitive, and their production processes can be challenging, but this book outlines techniques and concepts designed to overcome these challenges, emphasizing their role in durable and reliable propulsion systems in modern, safe, and environment-friendly shipping.Propeller shafts, water-lubricated stern tube bearings, problems frequently encountered with water-lubricated propeller shaft bearings and sliding bearings alongside solutions to these problems are all covered, as are the hydrodynamic properties of water-lubricated bearings, operation at low revolution speeds, high-speed bearings, hybrid bearings, and more. Foundational concepts of tribology related to friction, lubrication, wear, and fluid/solid and solid/solid interactions in ship stern tube and water-lubricated turbine machinery are also discussed.
This new edition draws upon the fundamentals of abrasive machining processes and the science of tribology to understand, predict, and improve abrasive machining processes. Each of the main elements of the abrasive machining system is looked at alongside the tribological factors that control the efficiency and quality of the processes described. The new edition has been updated to include a variety of industrial applications. Grinding and conditioning of grinding tools are dealt with in particular detail, and solutions are proposed for many of the most commonly experienced industrial problems, such as poor accuracy, poor surface quality, rapid tool wear, vibrations, workpiece burn, and high process costs. The entire book has been rewritten and restructured, with ten completely new chapters. Other new features include:
Tribology of Natural Fiber Polymer Composites, Second Edition, covers the availability and processing of natural fiber polymer composites and their structural, thermal, mechanical and tribological properties and performance. Environmental concerns are driving demand for biodegradable materials such as plant-based, natural fiber-reinforced polymer composites. These composites are fast replacing conventional materials in many industrial applications, especially in automobiles, where tribology (friction, lubrication and wear) is an important aspect.
High-Pressure Rheology for Quantitative Elastohydrodynamics, Second Edition, contains updated sections on scaling laws and thermal effects, including new sections on the importance of the pressure dependence of viscosity, the role of the localization limit of stress, and new material on the shear dependence of viscosity and temperature dependence viscosity. Since publication of the original edition, the experimental methods, the resulting property data and new correlations have resulted in a revolution in understanding of the mechanisms of film formation and the mechanical dissipation.
Tribology: Friction and Wear of Engineering Materials, Second Edition covers the fundamentals of tribology and the tribological response of all classes of materials, including metals, ceramics, and polymers. This fully updated and expanded book maintains its core emphasis on friction and wear of materials, but now also has a strengthened coverage of the more traditional tribological topics of contact mechanics and lubrication. It provides a solid scientific foundation that will allow readers to formulate appropriate solutions when faced with practical problems, as well as to design, perform and interpret meaningful tribological tests in the laboratory. Topics include the fundamentals of surface topography and contact mechanics, friction, lubrication, and wear (including tribo-corrosion), as well as surface engineering, selection of materials and design aspects. The book includes case studies on bearings, automotive tribology, manufacturing processes, medical engineering and magnetic data storage that illustrate some of the modern engineering applications in which tribological principles play vital roles. Each chapter is complemented by a set of questions suitable for self-study as well as classroom use. This book provides valuable material for advanced undergraduates and postgraduates studying mechanical engineering, materials science and other technical disciplines, and will also be a useful first reference point for any engineer or scientist who encounters tribological issues.
Impact Wear of Materials is entirely devoted to quantitative treatment of various forms of wear occurring in impact-loaded mechanical components. Impact wear is classified under two headings, namely `erosive' and `percussive' wear. In erosive wear, particle streams and liquid jets are discussed. The subject is developed with emphasis on material relations, stress analysis and the historical progress of research. In percussive wear, a wide variety of wear mechanisms is described.The author's experimental/analytical work created the groundwork for a general procedure of impact wear-law formulation, combining impact analysis with the physical wear mechanism. Ballistic impact and pivotal hammering, compound impact, the optimal wearpath, lubrication, plasticity, and flexible media are some of the topics considered.The book develops a new conceptual approach to impact, impact-originated wear and wear in general. It describes and utilizes the modern tools of observation in wear science. In mechanical analysis it emphasizes quantitative treatment, using such tools as finite element stress analysis, APL programming language etc., each applied with classic simplicity. Numerous photographs, tables, figures and examples are used throughout the text and the mathematical treatment strives for simplicity and conceptual clarity. The book is of value to mechanical component designers, analysts and researchers. It is also useful in science and engineering curricula at senior and graduate level and, although its appeal is primarily in tribology, machine design and materials science, its interdisciplinary language makes it accessible to any branch of the physical sciences and engineering.
Materials and mechanical engineering researchers studying wear, fretting, elastic indentation testing and other tribological processes frequently need closed-form solutions for various attributes of contacts. These characteristics include contact law, pressure distribution, internal state of stress induced and the influence of friction. Materials and mechanical engineering researchers studying wear, fretting, elastic indentation testing and other tribological processes frequently need closed-form solutions for various attributes of contacts. These characteristics include contact law, pressure distribution, internal state of stress induced and the influence of friction. These solutions, scattered throughout the applied mechanics literature, are difficult to locate, are presented using a range of solution techniques, and expressresults in a way that is suitable only for experts in the field. `Mechanics of Elastic Contacts' uses a consistent set of recipes for the solution of all relevant problems, presents results in the simplest possible forms, and contains summaries usingtabulated data. This reference source will provide a clear guide to elastic contacts for engineering designers, materials scientists and tribologists irrespective of their level of expertise in this important subject.
