Download or read book Structural Health Monitoring written by Daniel Balageas and published by John Wiley & Sons. This book was released on 2010-01-05 with total page 496 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is organized around the various sensing techniques used to achieve structural health monitoring. Its main focus is on sensors, signal and data reduction methods and inverse techniques, which enable the identification of the physical parameters, affected by the presence of the damage, on which a diagnostic is established. Structural Health Monitoring is not oriented by the type of applications or linked to special classes of problems, but rather presents broader families of techniques: vibration and modal analysis; optical fibre sensing; acousto-ultrasonics, using piezoelectric transducers; and electric and electromagnetic techniques. Each chapter has been written by specialists in the subject area who possess a broad range of practical experience. The book will be accessible to students and those new to the field, but the exhaustive overview of present research and development, as well as the numerous references provided, also make it required reading for experienced researchers and engineers.

Download or read book Masters Theses in the Pure and Applied Sciences written by Wade H. Shafer and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 426 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS)* at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dis semination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volumes were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 38 (thesis year 1993) a total of 13,787 thesis titles from 22 Canadian and 164 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this impor tant annual reference work. While Volume 38 reports theses submitted in 1993, on occasion, certain uni versities do report theses submitted in previous years but not reported at the time.

Download or read book Ceramic Materials written by Philippe Boch and published by John Wiley & Sons. This book was released on 2010-01-05 with total page 593 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is primarily an introduction to the vast family of ceramic materials. The first part is devoted to the basics of ceramics and processes: raw materials, powders synthesis, shaping and sintering. It discusses traditional ceramics as well as “technical” ceramics – both oxide and non-oxide – which have multiple developments. The second part focuses on properties and applications, and discusses both structural and functional ceramics, including bioceramics. The fields of abrasion, cutting and tribology illustrate the importance of mechanical properties. It also deals with the questions/answers of a ceramicist regarding electronuclear technology. As chemistry is an essential discipline for ceramicists, the book shows, in particular, what soft chemistry can contribute as a result of sol-gel methods.

Download or read book Carbon and High Performance Fibres Directory and Databook written by Trevor Starr and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 373 pages. Available in PDF, EPUB and Kindle. Book excerpt: PURPOSE Since the publication of the previous, Fifth Edition of this volume in 1991, the 'advanced' sector of the world-wide composites industry in particular, has seen many company changes in reorganisation, realignment and ownership. These changes have affected the raw material suppliers as well as those moulding the finished product. Changes in the demands of the aerospace, defence and allied industries have largely been the cause. That situation has been particularly true for those manufacturing and distributing reinforcement fibres and fabrics, necessitating this comprehensive Sixth Edition revision. However publication is also timely, because a major and important consequence is the better consideration now being given by the 'commercial' market sector, to the use - and advantages - of some of the carbon, aramid and other high-performance reinforcements, described within these pages. Although supplying at a much lower finished component cost than applies for the aerospace and defence markets, the total tonnage output answering the typically lower-performance requirements of the 'commercial' sector, is higher by many factors. Overall therefore, the summation of output tonnage and price, will continue to favour the latter. Nevertheless this 'commercial' market sector must, albeit slowly, ultimately benefit to a marked degree from an increasing technology spin-off, promoted to an extent somewhat earlier than might otherwise have been expected, by the noted changes in market place demand.

Download or read book Damage Mechanics of Composite Materials written by R. Talreja and published by Elsevier Science. This book was released on 1994 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: Damage mechanics is concerned with mechanics-based analyses of microstructural events in solids responsible for changes in their response to external loading. The microstructural events can occur as cracks, voids, slipped regions, etc., with a spatial distribution within the volume of a solid. If a solid contains oriented elements in its microsctructure, e.g. fibers, the heterogeneity and asisotropy aspects create situations which form a class of problems worthy of special treatment. This book deals with such treatments with particular emphasis on application to technological composite materials. Chapter one describes the basic principles underlying both the micromechanics approach and the continuum damage mechanics approach. It also reviews the relevant statistical concepts. The next three chapters are devoted to developments of the continuum damage mechanics approach related to characterization of damage with internal variables, evolution of damage and its coupling with other inelastic effects such as plasticity. Chapter 5 describes observations of damage from notches in composite laminates and puts forward some pragmatic modelling ideas for a complex damage configuration. The next two chapters form the bulk of the micromechanics approach in this volume. The first one deals with microcracking and the other with interfacial damage in composite materials.
