Book Synopsis Principles of Loads and Failure Mechanisms by : T Tinga
Download or read book Principles of Loads and Failure Mechanisms written by T Tinga and published by Springer Science & Business Media. This book was released on 2013-02-01 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: Failure of components or systems must be prevented by both designers and operators of systems, but knowledge of the underlying mechanisms is often lacking. Since the relation between the expected usage of a system and its failure behavior is unknown, unexpected failures often occur, with possibly serious financial and safety consequences. Principles of Loads and Failure Mechanisms. Applications in Maintenance, Reliability and Design provides a complete overview of all relevant failure mechanisms, ranging from mechanical failures like fatigue and creep to corrosion and electric failures. Both qualitative and quantitative descriptions of the mechanisms and their governing loads enable a solid assessment of a system’s reliability in a given or assumed operational context. Moreover, a unique range of applications of this knowledge in the fields of maintenance, reliability and design are presented. The benefits of understanding the physics of failure are demonstrated for subjects like condition monitoring, predictive maintenance, prognostics and health management, failure analysis and reliability engineering. Finally, the role of these mechanisms in design processes and design for maintenance are illustrated.

Book Synopsis Reliability of Maintained Systems Subjected to Wear Failure Mechanisms by : Franck Bayle
Download or read book Reliability of Maintained Systems Subjected to Wear Failure Mechanisms written by Franck Bayle and published by John Wiley & Sons. This book was released on 2019-04-10 with total page 215 pages. Available in PDF, EPUB and Kindle. Book excerpt: Today, the reliability of systems has become a major issue in most industrial applications. The theoretical approach to estimating reliability was largely developed in the 1960s for maintenance-free systems, and more recently, in the late 1990s, it was developed for maintenance-based systems. Customers’ expectations concerning reliability (as well as maintenance, safety, etc.) are growing ever more demanding over the generations of systems. However, the theoretical methods used to handle the systems are not suitable when aging mechanisms are present. This book proposes a theoretical approach to estimate all of these quantities correctly. In addition to the theoretical aspect, it details a number of issues that any industrial system will meet sooner or later, whether due to design flaws, the batch of components, manufacturing problems or new technologies that result in the aging of mechanisms during their operational use.

Book Synopsis Reliability Growth by : Panel on Reliability Growth Methods for Defense Systems
Download or read book Reliability Growth written by Panel on Reliability Growth Methods for Defense Systems and published by National Academy Press. This book was released on 2015-03-01 with total page 235 pages. Available in PDF, EPUB and Kindle. Book excerpt: A high percentage of defense systems fail to meet their reliability requirements. This is a serious problem for the U.S. Department of Defense (DOD), as well as the nation. Those systems are not only less likely to successfully carry out their intended missions, but they also could endanger the lives of the operators. Furthermore, reliability failures discovered after deployment can result in costly and strategic delays and the need for expensive redesign, which often limits the tactical situations in which the system can be used. Finally, systems that fail to meet their reliability requirements are much more likely to need additional scheduled and unscheduled maintenance and to need more spare parts and possibly replacement systems, all of which can substantially increase the life-cycle costs of a system. Beginning in 2008, DOD undertook a concerted effort to raise the priority of reliability through greater use of design for reliability techniques, reliability growth testing, and formal reliability growth modeling, by both the contractors and DOD units. To this end, handbooks, guidances, and formal memoranda were revised or newly issued to reduce the frequency of reliability deficiencies for defense systems in operational testing and the effects of those deficiencies. "Reliability Growth" evaluates these recent changes and, more generally, assesses how current DOD principles and practices could be modified to increase the likelihood that defense systems will satisfy their reliability requirements. This report examines changes to the reliability requirements for proposed systems; defines modern design and testing for reliability; discusses the contractor's role in reliability testing; and summarizes the current state of formal reliability growth modeling. The recommendations of "Reliability Growth" will improve the reliability of defense systems and protect the health of the valuable personnel who operate them.
Book Synopsis Failure Mechanisms in Alloys by : George Pantazopoulos
Download or read book Failure Mechanisms in Alloys written by George Pantazopoulos and published by . This book was released on 2020 with total page 476 pages. Available in PDF, EPUB and Kindle. Book excerpt: The era of lean production and excellence in manufacturing, advancing with sustainable development, demands the rational utilization of raw materials and energy resources, adopting cleaner and environmentally-friendly industrial processes. In view of the new industrial revolution, through digital transformation, the exploitation of smart and sophisticated materials systems, the need of minimizing scrap and increasing efficiency, reliability and lifetime and, on the other hand, the pursuit of fuel economy and limitation of carbon footprint, are necessary conditions for the imminent growth in a highly competitive economy. Failure analysis is an interdisciplinary scientific topic, reflecting the opinions and interpretations coming from a systematic evidence-gathering procedure, embracing various important sectors, imparting knowledge, and substantiating improvement practices. The deep understanding of material/component role (e.g., rotating shaft, extrusion die, gas pipeline) and properties will be of central importance for fitness for purpose in certain industrial processes and applications. Finally, it is hoped and strongly believed that the accumulation of additional knowledge in the field of failure mechanisms and the adoption of the principles, philosophy, and deep understanding of failure analysis process approach will strongly promote the learning concept, as a continuously evolving process leading to personal and social progress and prosperity.
Book Synopsis Reliability Physics and Engineering by : J. W. McPherson
Download or read book Reliability Physics and Engineering written by J. W. McPherson and published by Springer Science & Business Media. This book was released on 2010-08-05 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: All engineers could bene?t from at least one course in reliability physics and engineering. It is very likely that, starting with your very ?rst engineering po- tion, you will be asked — how long is your newly developed device expected to last? This text was designed to help you to answer this fundamentally important question. All materials and devices are expected to degrade with time, so it is very natural to ask — how long will the product last? The evidence for material/device degradation is apparently everywhere in nature. A fresh coating of paint on a house will eventually crack and peel. Doors in a new home can become stuck due to the shifting of the foundation. The new ?nish on an automobile will oxidize with time. The tight tolerances associated with ?nely meshed gears will deteriorate with time. Critical parameters associated with hi- precision semiconductor devices (threshold voltages, drive currents, interconnect resistances, capacitor leakages, etc.) will degrade with time. In order to und- stand the lifetime of the material/device, it is important to understand the reliability physics (kinetics) for each of the potential failure mechanisms and then be able to develop the required reliability engineering methods that can be used to prevent, or at least minimize the occurrence of, device failure.

Download or read book Failure Analysis written by Marius Bazu and published by Wiley. This book was released on 2011-04-25 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Failure analysis is the preferred method to investigate product or process reliability and to ensure optimum performance of electrical components and systems. The physics-of-failure approach is the only internationally accepted solution for continuously improving the reliability of materials, devices and processes. The models have been developed from the physical and chemical phenomena that are responsible for degradation or failure of electronic components and materials and now replace popular distribution models for failure mechanisms such as Weibull or lognormal. Reliability engineers need practical orientation around the complex procedures involved in failure analysis. This guide acts as a tool for all advanced techniques, their benefits and vital aspects of their use in a reliability programme. Using twelve complex case studies, the authors explain why failure analysis should be used with electronic components, when implementation is appropriate and methods for its successful use. Inside you will find detailed coverage on: a synergistic approach to failure modes and mechanisms, along with reliability physics and the failure analysis of materials, emphasizing the vital importance of cooperation between a product development team involved the reasons why failure analysis is an important tool for improving yield and reliability by corrective actions the design stage, highlighting the ‘concurrent engineering' approach and DfR (Design for Reliability) failure analysis during fabrication, covering reliability monitoring, process monitors and package reliability reliability resting after fabrication, including reliability assessment at this stage and corrective actions a large variety of methods, such as electrical methods, thermal methods, optical methods, electron microscopy, mechanical methods, X-Ray methods, spectroscopic, acoustical, and laser methods new challenges in reliability testing, such as its use in microsystems and nanostructures This practical yet comprehensive reference is useful for manufacturers and engineers involved in the design, fabrication and testing of electronic components, devices, ICs and electronic systems, as well as for users of components in complex systems wanting to discover the roots of the reliability flaws for their products.

Available in PDF, EPUB and Kindle. Book excerpt: This book traces the evolution of theory of structures and strength of materials - the development of the geometrical thinking of the Renaissance to become the fundamental engineering science discipline rooted in classical mechanics. Starting with the strength experiments of Leonardo da Vinci and Galileo, the author examines the emergence of individual structural analysis methods and their formation into theory of structures in the 19th century. For the first time, a book of this kind outlines the development from classical theory of structures to the structural mechanics and computational mechanics of the 20th century. In doing so, the author has managed to bring alive the differences between the players with respect to their engineering and scientific profiles and personalities, and to create an understanding for the social context. Brief insights into common methods of analysis, backed up by historical details, help the reader gain an understanding of the history of structural mechanics from the standpoint of modern engineering practice. A total of 175 brief biographies of important personalities in civil and structural engineering as well as structural mechanics plus an extensive bibliography round off this work.

Book Synopsis Principles of Engineering Geology by : P.B. Attewell
Download or read book Principles of Engineering Geology written by P.B. Attewell and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 1075 pages. Available in PDF, EPUB and Kindle. Book excerpt: 'Engineering geology' is one of those terms that invite definition. The American Geological Institute, for example, has expanded the term to mean 'the application of the geological sciences to engineering practice for the purpose of assuring that the geological factors affecting the location, design, construction, operation and mainten ance of engineering works are recognized and adequately provided for'. It has also been defined by W. R. Judd in the McGraw-Hill Encyclopaedia of Science and Technology as 'the application of education and experience in geology and other geosciences to solve geological problems posed by civil engineering structures'. Judd goes on to specify those branches of the geological or geo-sciences as surface (or surficial) geology, structural/fabric geology, geohydro logy, geophysics, soil and rock mechanics. Soil mechanics is firmly included as a geological science in spite of the perhaps rather unfortunate trends over the years (now happily being reversed) towards purely mechanistic analyses which may well provide acceptable solutions for only the simplest geology. Many subjects evolve through their subject areas from an interdisciplinary background and it is just such instances that pose the greatest difficulties of definition. Since the form of educational development experienced by the practitioners of the subject ulti mately bears quite strongly upon the corporate concept of the term 'engineering geology', it is useful briefly to consider that educational background.

Book Synopsis The Principles of Building Construction by : Madan Mehta
Download or read book The Principles of Building Construction written by Madan Mehta and published by Pearson. This book was released on 1997 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: Using an innovative, integrated approach, this book explores the linkages between the science of materials and the practices of construction to help future architects and builders deal more critically with the ever-increasing array of new materials and the consequent increase in the complexities of construction. This book presents and integrates the scientific principles of building materials and construction and their relationships with actual practices. Issues are covered that are relevant to every building type regardless of whether the primary material used in the building is wood, masonry, steel, or concrete. It begins with a brief treatment of building codes and standards since all building construction must conform to building codes as a minimum requirement. It provides full-chapter coverage of structural, thermal, fire related properties, transparency, air infiltration, water vapor and (bulk) water penetration, and dimensional control in buildings. It offers a flexible organization, so content can be covered sequentially or in parts. The U.S. system of units is used primarily throughout, but gives the SI system equal treatment.
Book Synopsis Inelastic Analysis of Structures under Variable Loads by : Dieter Weichert
Download or read book Inelastic Analysis of Structures under Variable Loads written by Dieter Weichert and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: The question whether a structure or a machine component can carry the applied loads, and with which margin of safety, or whether it will become unserviceable due to collapse or excessive inelastic deformations, has always been a major concern for civil and mechanical engineers. The development of methods to answer this technologically crucial question without analysing the evolution of the system under varying loads, has a long tradition that can be traced back even to the times of emerging mechanical sciences in the early 17th century. However, the scientific foundations of the theories underlying these methods, nowadays frequently called "direct", were established sporadically in the Thirties of the 20th century and systematically and rigorously in the Fifties. Further motivations for the development of direct analysis techniques in applied mechanics of solids and structures arise from the circumstance that in many engineering situations the external actions fluctuate according to time histories not a priori known except for some essential features, e.g. variation intervals. In such situations the critical events (or "limit states") to consider, besides plastic collapse, are incremental collapse (or "ratchetting") and alternating plastic yielding, namely lack of "shakedown". Non evolutionary, direct methods for ultimate limit state analysis of structures subjected to variably-repeated external actions are the objectives of most papers collected in this book, which also contains a few contributions on related topics.
