Tribology is a branch of science that deals with machine elements and their friction, wear, and lubrication. Tribology of Machine Elements - Fundamentals and Applications presents the fundamentals of tribology, with chapters on its applications in engines, metal forming, seals, blasting, sintering, laser texture, biomaterials, and grinding.

This book constitutes the refereed proceedings of the 7th International Workshop on Intelligent Virtual Agents, IVA 2007, held in Paris, France, September 2007. The 19 revised full papers and 12 revised short papers presented together with five invited talks and the abstracts of 32 poster papers are organized in topical sections on rendering and analysis, culture and identity, behavior models, feedback models, dialogues, applications, evaluation, gaze models and emotions.
In the world of modern engineering, rigorous and definite design methodologies are needed. However, many parts of engineering design are performed in either an ad-hoc manner or based on the intuition of the engineer. This is the first book to look at both stages of the design process – conceptual design and detailed design – and detail design methodologies for every step of the design process. Case studies show how practical design problems can be solved with analytic design methods. This book is an excellent introduction to the subject. The book’s practical focus will make the book useful to practicing engineers as a practical handbook of design.
Elasto-Hydrodynamic Lubrication deals with the mechanism of elasto-hydrodynamic lubrication, that is, the lubrication regime in operation over the small areas where machine components are in nominal point or line contact. The lubrication of rigid contacts is discussed, along with the effects of high pressure on the lubricant and bounding solids. The governing equations for the solution of elasto-hydrodynamic problems are presented. 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.
This text addreseses the topic of surface roughness, how to measure and describe it, and what practical problems it might cause. Updated to include advances in measurement and characterization, this second edition introduces modern instruments, including laser interferometers and AFMs, and there are sections on fractals and motif analysis. Problems of 3D surface measurement and description are extensively treated. Manufacturing and production engineers, optical and QC engineers, tribologists and many other applied scientists should find this book useful.
Este livro mostra a trajetória de Clovis Tramontina, que em muitos aspectos se confunde com a da empresa que carrega seu sobrenome. Nem Clovis nem a Tramontina seguem as cartilhas tradicionais dos homens e das empresas bem-sucedidos. O livro revela um homem simples, direto, objetivo, impulsivo, intempestivo, impaciente, que tem pressa, mas nos apresenta também um ser frágil, sentimental, humano, numa soma complexa que o faz destacar-se por onde passe, que não tem medo de ousar, errar, expor-se e ir em frente. A jornalista Fátima Torri, que coordenou a edição do livro, alerta: “Não se enganem. Ao final da leitura vocês verão um líder do avesso. Generoso por mostrar-se. Nem sempre perfeito. Demasiadamente humano.”
Descripción del editor: "heet forming fundamentals are thoroughly addressed in this comprehensive reference for the practical and efficient use of sheet forming technologies. The principle variables of sheet forming-including the interactions between variables-are clearly explained, as a basic foundation for the most effective use of computer aided modeling in process and die design.Topics include stress analysis, formability criteria, tooling, and materials for sheet forming. The book also covers the latest developments in sheet metal forming technology, including servo-drive presses and their applications, and advanced cushion systems in mechanical and hydraulic presses."
