Surface Effects and Contact Mechanics XI


Book Description

Containing the papers from the eleventh biennial conference on the topic, first held in 1993, this book covers contact mechanics and surface effects and their interaction, so important in modern engineering. The life and performance of structural components is affected by surface conditions such as wear, corrosion and, high cycle fatigue. Surface treatments that address contact conditions can reduce costs by extending the life of components. Hence the importance of the conference discussions.The book's papers cover such matters as Experimental and measurement tests; Fracture fatigue and mechanics; Surface modification; Surface problems in contact mechanics; Thick and thin coatings; Heat transfers; Multiscale experiments and modelling; Computer simulation; Biocompatible materials; Vacuum technologies; Residual stress problems; Tribomechanics; Case studies.




Handbook of Contact Mechanics


Book Description

This open access book contains a structured collection of the complete solutions of all essential axisymmetric contact problems. Based on a systematic distinction regarding the type of contact, the regime of friction and the contact geometry, a multitude of technically relevant contact problems from mechanical engineering, the automotive industry and medical engineering are discussed. In addition to contact problems between isotropic elastic and viscoelastic media, contact problems between transversal-isotropic elastic materials and functionally graded materials are addressed, too. The optimization of the latter is a focus of current research especially in the fields of actuator technology and biomechanics. The book takes into account adhesive effects which allow access to contact-mechanical questions about micro- and nano-electromechanical systems. Solutions of the contact problems include both the relationships between the macroscopic force, displacement and contact length, as well as the stress and displacement fields at the surface and, if appropriate, within the half-space medium. Solutions are always obtained with the simplest available method - usually with the method of dimensionality reduction (MDR) or approaches which use the solution of the non-adhesive normal contact problem to solve the respective contact problem.




Contact Mechanics


Book Description

This treatise is concerned with the stresses and deformation of solid bodies in contact with each other, along curved surfaces which touch initially at a point or along a line. Examples are a railway wheel and rail, or a pair of gear wheel teeth. Professor Johnson first reviews the development of the theory of contact stresses since the problem was originally addressed by H. Hertz in 1882. Next he discusses the influence of friction and the topographical roughness of surfaces, and this is incorporated into the theory of contact mechanics. An important feature is the treatment of bodies which deform plastically or viscoelastically. In addition to stationary contact, an appreciable section of the book is concerned with bodies which are in sliding or rolling contact, or which collide.

These are the subjects of a biennial conference first held in 1993, the papers from the latest of which are collected in this volume. The book discusses Computer simulation; Surface modification; Surface treatments; Surface problems in contact mechanics; Contact mechanics; Applications and case studies; Indentation and hardness; Thick and thin coatings; Corrosion problems; Nano-characterisation; Test methodology; Multiscale experiments and modelling; and Fracture fatigue and mechanics.




Contact Problems


Book Description

L.A. Galin’s book on contact problems is a remarkable work. Actually there are two books: the first, published in 1953 deals with contact problems in the classical theory of elasticity; this is the one that was translated into English in 1961. The second book, published in 1980, included the first, and then had new sections on contact problems for viscoelastic materials, and rough contact problems; this section has not previously been translated into English. In this new translation, the original text and the mathematical analysis have been completely revised, new material has been added, and the material appearing in the 1980 Russian translation has been completely rewritten. In addition there are three essays by students of Galin, bringing the analysis up to date.




Computer Methods and Experimental Measurements for Surface Effects and Contact Mechanics VIII


Book Description

The importance of contact and surface problems in modern engineering and their combined effects has led to the Eighth International Conference on Computer Methods and Experimental Measurements for Surface and Contact Mechanics. Nowadays the importance of contact and surface problems in many technological fields is well understood: they are complex and inherently non-linear due to their moving boundaries and the different properties of materials, particularly along the contact surfaces. Structural components fail from wear, corrosion, high cycle fatigue etc., that is to say affected and initiated by the surface conditions. The use of surface treatments can reduce the cost of components and extend the life of the elements. Their effect is of particular importance in the case of surfaces undergoing contact, a problem which is addressed throughout the book. Topics featured: Surface Treatment; Surface problems in Contact Mechanics; Fracture Mechanics; Coupled analysis and experiments; Thin Coatings; Thick Coatings; Contact Mechanics; Material Surface in Contact; Applications and Case Studies.




Contact Mechanics


Book Description

This book describes the solution of contact problems with an emphasis on idealized (mainly linear) elastic problems that can be treated with elementary analytical methods. General physical and mathematical features of these solutions are highlighted. Topics covered include the contact of rough surfaces and problems involving adhesive (e.g. van der Waals) forces. The author is a well-known researcher in the subject with hands-on experience of the topics covered and a reputation for lucid explanations. The target readership for the book includes researchers who encounter contact problems but whose primary focus is not contact mechanics. Coverage is also suitable for a graduate course in contact mechanics and end-of-chapter problems are included.




Surface Effects and Contact Mechanics including Tribology XII


Book Description

The book contains papers from the twelfth in a series of biennial conferences, first held in 1993, on the topics of contact mechanics and surface effects and their interaction. In general, structural components fail by wear, corrosion and fatigue, that is to say affected and initiated by surface conditions. Consequently, it is often appropriate to modify the surface layer of a base material or coat it, so as to provide an enhanced performance or longer life. However, in many cases it is the combined effect of wear and corrosion that is damaging, contributing to complexity in determining the proper approach. The surface treatment chosen should be suitably related to the problem to be solved. The necessary thickness of the coating depends largely on the applied loading and environmental conditions. The papers in the book address novel protective layers for advances in sliding wear and low friction. The contents cover topics such as: Experimental and Measurement Tests; Surface Modification; Surface Problems in Contact Mechanics; Thick and Thin Coatings; Tribomechanics; Computer Simulation.




Materials Characterisation VI


Book Description

This book contains papers to be presented at the Sixth International Conference on the topic. Materials modelling and characterisation have become ever more closely intertwined. Characterisation, in essence, connects the abstract material model with the real-world behaviour of the material in question. Characterisation of complex materials often requires a combination of experimental and computational techniques. The conference is convened biennially to facilitate the sharing of recent work between researchers who use computational methods, those who perform experiments, and those who do both, in all areas of materials characterisation.The papers cover such topics as: Computational models and experiments; Mechanical characterisation and testing; Micro and macro materials characterisation; Corrosion problems; Innovative experimental technologies; Recycled materials; Thermal analysis; Advances in composites; Cementitious materials; Structural health monitoring; Energy materials.
