Download Industrial Tribology Book in PDF, Epub and Kindle
Covering energy-saving technologies and how these are incorporated into component design, this book is relevant to many industries, including automotive engineering, and discusses the topical issue of sustainability in industry. This book details recent fundamental developments in the field of tribology in industrial systems. Tribology has advanced significantly in recent years. Tribological performance depends on external parameters such as contact pressure at the interface, system temperature, relative speed between bodies and contact behaviour. Through ensuring that mechanisms work in an energy-efficient manner and minimizing wear, engineers should seek to implement the study of tribology to improve the life of machinery within industry. Essential to the study of component design and condition monitoring, the book touches upon topics such as gears, bearings and clutches. Additionally, it discusses tribology’s relation to Industry 4.0 and incorporates the results from cutting-edge research. Industrial Tribology: Sustainable Machinery and Industry 4.0 will be of interest to all engineers working in industry and involved in mechanical engineering, material engineering, mechanisms and component design and automotive engineering.

Download Nonlinearities and Major Mechanisms in Presliding Friction and Energy Dissipation at Asperity-scale and Rough Surface Contacts Book in PDF, Epub and Kindle
Behavior of a system with friction at the interface is inherently nonlinear. Nonlinearities associated to interfacial mechanics primarily are the onset of sliding and energy dissipation. Firstly, to understand friction a finite element model is used to simulate sliding inception of a rigid flat on a deformable sphere under combined normal and tangential loading. Sliding inception is treated as the loss of tangential contact stiffness under combined effects of plasticity, crack propagation and interfacial slip. For fully adhered contact condition, plasticity is shown to be the dominant failure mechanism. Interplay of plasticity and interfacial slip is found to govern the onset of sliding for higher local friction coefficients. Furthermore, the single asperity results are incorporated in a statistical model of nominally flat rough surfaces under combined normal and tangential loading to investigate the stochastic effects due to surface roughness and material property uncertainties. The results show that the static coefficient of friction strongly depends on the normal load, material properties, local interfacial strength (adhesive friction component) and roughness parameters. The proposed model can be used as a measure for uncertainties that significantly influence the static friction coefficient. To investigate energy dissipation at an interface, a low cyclic tangential load is applied to obtain the hysteresis loops for the spherical model. The energy dissipation is studied under the influence of elastic mismatch, plasticity and varying phase difference between tangential and normal load. The energy losses are then correlated against the maximum tangential load as a power-law where the exponents show the degree of nonlinearity. Inducing a phase difference of 90 degrees between normal and tangential loads lead power-law exponents closer to 2; i.e., quadratic dependence of energy dissipation on tangential force. The results from the asperity scale are once again extended to the rough surface scale to study the effects of roughness parameters. The power-law exponent is found to be largely independent of roughness parameters as asperity density, asperity height distribution and fractal dimension. Achieving power-law exponents closer to 2 can be viewed as a first step in devising a predictive interfacial damping for frictional contacts.

Download Micromechanics of Contact and Interphase Layers Book in PDF, Epub and Kindle
Micromechanics provides a link between the structure and the properties at different scales of observation. This book deals with micromechanical analysis of interfaces and interface layers and presents several modelling tools. These range from the rigorous method of asymptotic expansions to practical finite element simulations, suitable for this class of problems. The corresponding two parts of the book are self-contained, so they can be read separately.

Download Sliding Friction Book in PDF, Epub and Kindle
Sliding friction is one of the oldest problems in physics and certainly one of the most important from a practical point of view. The ability to produce durable low-friction surfaces and lubricant fluids has become an important factor in the miniaturization of moving components in many technological devices, e.g., magnetic storage, recording systems, miniature motors and many aerospace components. This book will be useful to physicists, chemists, materials scientists, and engineers who want to understand sliding friction. The book (or parts of it) could also form the basis for a modern undergraduate or graduate course on tribology.
