This unique volume imparts practical information on the operation, maintenance, and modernization of heavy performance machines such as lignite mine machines, bucket wheel excavators, and spreaders. Problems of large scale machines (mega machines) are highly specific and not well recognized in the common mechanical engineering environment. Prof. Rusinski and his co-authors identify solutions that increase the durability of these machines as well as discuss methods of failure analysis and technical condition assessment procedures. "Surface Mining Machines: Problems in Maintenance and Modernization" stands as a much-needed guidebook for engineers facing the particular challenges of heavy performance machines and offers a distinct and interesting demonstration of scale-up issues for researchers and scientists from across the fields of machine design and mechanical engineering.

This multi-contributed volume provides a practical, applications-focused introduction to nonlinear acoustical techniques for nondestructive evaluation. Compared to linear techniques, nonlinear acoustical/ultrasonic techniques are much more sensitive to micro-cracks and other types of small distributed damages. Most materials and structures exhibit nonlinear behavior due to the formation of dislocation and micro-cracks from fatigue or other types of repetitive loadings well before detectable macro-cracks are formed. Nondestructive evaluation (NDE) tools that have been developed based on nonlinear acoustical techniques are capable of providing early warnings about the possibility of structural failure before detectable macro-cracks are formed. This book presents the full range of nonlinear acoustical techniques used today for NDE. The expert chapters cover both theoretical and experimental aspects, but always with an eye towards applications. Unlike other titles currently available, which treat nonlinearity as a physics problem and focus on different analytical derivations, the present volume emphasizes NDE applications over detailed analytical derivations. The introductory chapter presents the fundamentals in a manner accessible to anyone with an undergraduate degree in Engineering or Physics and equips the reader with all of the necessary background to understand the remaining chapters. This self-contained volume will be a valuable reference to graduate students through practising researchers in Engineering, Materials Science, and Physics. Represents the first book on nonlinear acoustical techniques for NDE applications Emphasizes applications of nonlinear acoustical techniques Presents the fundamental physics and mathematics behind nonlinear acoustical phenomenon in a simple, easily understood manner Covers a variety of popular NDE techniques based on nonlinear acoustics in a single volume

This book gives an overview of the existing self-healing nanotextured vascular approaches. It describes the healing agents used in engineering self-healing materials as well as the fundamental physicochemical phenomena accompanying self-healing. This book also addresses the different fabrication methods used to form core-shell nanofiber mats. The fundamental theoretical aspects of fracture mechanics are outlined. A brief theoretical description of cracks in brittle elastic materials is given and the Griffith approach is introduced. The fracture toughness is described, including viscoelastic effects. Critical (catastrophic) and subcritical (fatigue) cracks and their growth are also described theoretically. The adhesion and cohesion energies are introduced as well, and the theory of the blister test for the two limiting cases of stiff and soft materials is developed. In addition, the effect of non-self-healing nanofiber mats on the toughening of ply surfaces in composites is discussed. The book also presents a brief description of the electrochemical theory of corrosion crack growth. All the above-mentioned phenomena are relevant in the context of self-healing materials.

This book presents a comprehensive mathematical approach for solving stochastic magnetic field problems. It discusses variability in material properties and geometry, with an emphasis on the preservation of structural physical and mathematical properties. It especially addresses uncertainties in the computer simulation of magnetic fields originating from the manufacturing process. Uncertainties are quantified by approximating a stochastic reformulation of the governing partial differential equation, demonstrating how statistics of physical quantities of interest, such as Fourier harmonics in accelerator magnets, can be used to achieve robust designs. The book covers a number of key methods and results such as: a stochastic model of the geometry and material properties of magnetic devices based on measurement data; a detailed description of numerical algorithms based on sensitivities or on a higher-order collocation; an analysis of convergence and efficiency; and the application of the developed model and algorithms to uncertainty quantification in the complex magnet systems used in particle accelerators.

Biomechanical engineering is involved with creating and producing a variety of products in everyday use, from environmentally safe plastics to various foods, fabrics, and medicines. A combination of engineering and biology, it is a fast-growing field with many new and exciting opportunities in genetic engineering and biotechnology. However, research surrounding biomechanical applications is scattered and often restricted, leading to the need for a comprehensive publication of the recent advances and developments in this emerging field. Design, Development, and Optimization of Bio-Mechatronic Engineering Products provides pivotal research on the application of combining mechanical engineering with human biological systems in order to develop bio-mechatronic products like pacemakers, artificial kidney replacements, artificial hearts, and new joints or limbs to better and more accurately monitor and advance human health. While highlighting topics such as orthotic devices, inter-electrode gap, and biomaterial applications, this publication explores producing artificial material to work in sync with the human body. This book is ideally designed for engineers, health professionals, technology developers, researchers, academicians, and students.

This fully revised and up-dated second edition of "Process Pump Selection" represents the distilled expereince of a team of highly regarded engineers working for large process companies over a period of more than 20 years. It is a classic example of experiential learning, where experience witrh hundreds of pumping installaitons has been synthesized to provide a series of empirical formulae, design guides, and codes of practice for pump users. It is the very essence of professional engineering practice. This text eases the daunting task that faces a process industries' engineer employed in th eprocess industries and responsible for the specificaiton, selection, and purchase of process equipment. There are many national and international specifications laying down design and construcitonal requirements. These deal mainly with the shape and safety issues, but they are no help in selecting a pump suitable for a given duty. Further manufacturers' data give only the basic performance of a pump: the effect of fluid properties and performance limits, as well as control requirements, are not included in catalogue material. This volume provides essential guidelines, based on the operaitonal experience of large numbers of pumping installations over many years on a diverse range of duties and process plants.
