Fundamentals and Applications of Ultrasonic Waves by J. David N. Cheeke Pdf
Written at an intermediate level in a way that is easy to understand, Fundamentals and Applications of Ultrasonic Waves, Second Edition provides an up-to-date exposition of ultrasonics and some of its main applications. Designed specifically for newcomers to the field, this fully updated second edition emphasizes underlying physical concepts over mathematics. The first half covers the fundamentals of ultrasonic waves for isotropic media. Starting with bulk liquid and solid media, discussion extends to surface and plate effects, at which point the author introduces new modes such as Rayleigh and Lamb waves. This focus on only isotropic media simplifies the usually complex mathematics involved, enabling a clearer understanding of the underlying physics to avoid the complicated tensorial description characteristic of crystalline media. The second part of the book addresses a broad spectrum of industrial and research applications, including quartz crystal resonators, surface acoustic wave devices, MEMS and microacoustics, and acoustic sensors. It also provides a broad discussion on the use of ultrasonics for non-destructive evaluation. The author concentrates on the developing area of microacoustics, including exciting new work on the use of probe microscopy techniques in nanotechnology. Focusing on the physics of acoustic waves, as well as their propagation, technology, and applications, this book addresses viscoelasticity, as well as new concepts in acoustic microscopy. It updates coverage of ultrasonics in nature and developments in sonoluminescence, and it also compares new technologies, including use of atomic force acoustic microscopy and lasers. Highlighting both direct and indirect applications for readers working in neighboring disciplines, the author presents particularly important sections on the use of microacoustics and acoustic nanoprobes in next-generation devices and instruments.
Bone Quantitative Ultrasound by Pascal Laugier,Quentin Grimal Pdf
Many significant achievements in new ultrasound technologies to measure bone and models to elucidate the interaction and the propagation of ultrasonic waves in complex bone structures have been reported over the past ten years. Impaired bone remodeling affects not only the trabecular compartment but also the cortical one. Despite the crucial contribution of the cortical structure to the whole bone mechanical competence, cortical bone was understudied for a long time. A paradigm shift occurred around 2010, with a special focus placed on the importance of cortical bone. This has sparkled a great deal of interest in new ultrasound techniques to assess cortical bone. While our book ‘Bone Quantitative Ultrasound’ published in 2011 emphasized techniques to measure trabecular bone, this new book is devoted for a large part to the technologies introduced recently to measure cortical bone. These include resonant ultrasound spectroscopy, guided waves, scattering, and pulse-echo and tomography imaging techniques. Instrumentation, signal processing techniques and models used are detailed. Importantly, the data accumulated in recent years such as anisotropic stiffness, elastic engineering moduli, compression and shear wave speeds of cortical bones from various skeletal sites are presented comprehensively. A few chapters deal with the recent developments achieved in quantitative ultrasound of trabecular bone. These include (i) scattering-based approaches and their application to measure skeletal sites such as the spine and proximal femur and (ii) approaches exploiting the poro-elastic nature of bone. While bone fragility and osteoporosis are still the main motivation for developing bone QUS, this Book also includes chapters reporting ultrasound techniques developed for other applications of high interest such as 3-D imaging of the spine, assessment of implant stability and transcranial brain imaging. This book, together with the book ‘Bone Quantitative Ultrasound’ published in 2011 will provide a comprehensive overview of the methods and principles used in bone quantitative ultrasound and will be a benchmark for all novice or experienced researchers in the field. The book will offer recent experimental results and theoretical concepts developed so far and would be intended for researchers, graduate or undergraduate students, engineers, and clinicians who are involved in the field. The book should be considered as a complement to the first book publisher in 2011, rather than a second edition, in the sense that basic notions already presented in the first book are not repeated.
Nonlinear Ultrasonic and Vibro-Acoustical Techniques for Nondestructive Evaluation by Tribikram Kundu Pdf
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

Ultrasonic Testing of Materials by Josef Krautkrämer,Herbert Krautkrämer Pdf
Nondestructive testing of solid material using ultrasonic waves, for defects such as cavities, nonbonding, and strength variations, is treated in this book from the physical fundamentals of ultrasonics and materials up to the most sophisticated methods. The book is written at a level which should make it accessible to readers with some knowledge of technical mathematics. Physical laws are explained in elementary terms, and more sophisticated treatments are also indicated. After the fundamentals, instrumentation and its application is extensively reported. Tricks and observations from thirty years of experience in the field are included. The third part of the book presents test problems related to special materials or ranges of modern heavy industry, including recent applications such as those in nuclear power plants. This fourth edition features improved presentation of certain fundamental physical facts, updated reports on electronic instrumentation, and new applications in the nuclear and space industries.
