Ultrasonic methods have been very popular in nondestructive testing and characterization of materials. This book deals with both industrial ultrasound and medical ultrasound. The advantages of ultrasound include flexibility, low cost, in-line operation, and providing data in both signal and image formats for further analysis. The book devotes 11 chapters to ultrasonic methods. However, ultrasonic methods can be much less effective with some applications. So the book also has 14 chapters catering to other or advanced methods for nondestructive testing or material characterization. Topics like structural health monitoring, Terahertz methods, X-ray and thermography methods are presented. Besides different sensors for nondestructive testing, the book places much emphasis on signal/image processing and pattern recognition of the signals acquired.

This book describes in detail the physical and mathematical foundations of ultrasonic phased array measurements. The book uses linear systems theory to develop a comprehensive model of the signals and images that can be formed with phased arrays. Engineers working in the field of ultrasonic nondestructive evaluation (NDE) will find in this approach a wealth of information on how to design, optimize and interpret ultrasonic inspections with phased arrays. The fundamentals and models described in the book will also be of significant interest to other fields, including the medical ultrasound and seismology communities. A unique feature of this book is that it presents a unified theory of imaging with phased arrays that shows how common imaging methods such as the synthetic aperture focusing technique (SAFT), the total focusing method (TFM), and the physical optics far field inverse scattering (POFFIS) imaging method are all simplified versions of more fundamental and quantitative imaging approaches, called imaging measurement models. To enhance learning, this book first describes the fundamentals of phased array systems using 2-D models, so that the complex 3-D cases normally found in practice can be more easily understood. In addition to giving a detailed discussion of phased array systems, Fundamentals of Ultrasonic Phased Arrays also provides MATLAB® functions and scripts, allowing the reader to conduct simulations of ultrasonic phased array transducers and phased array systems with the latest modeling technology.

Ultrasound is currently used in a wide spectrum of applications ranging from medical imaging to metal cutting. This book is about using ultrasound in nondestructive evaluation (NDE) inspections. Ultrasonic NDE uses high-frequency acoustic/elastic waves to evaluate components without affecting their integrity or performance. This technique is commonly used in industry (particularly in aerospace and nuclear power) to inspect safety-critical parts for flaws during in-service use. Other important uses of ultrasonic NDE involve process control functions during manufacturing and fundamental materials characterization studies. It is not difficult to set up an ultrasonic NDE measurement system to launch waves into a component and monitor the waves received from defects, such as cracks, even when those defects are deep within the component. It is difficult however to interpret quantitatively the signals received in such an ultrasonic NDE measurement process. For example based on the ultrasonic signal received from a crack, what is the size, shape, and orientation of the crack producing the signal? Answering such questions requires evaluation procedures based on a detailed knowledge of the physics of the entire ultrasonic measurement process. One approach to obtaining such knowledge is to couple quantitative experiments closely with detailed models of the entire ultrasonic measurement system itself. We refer to such models here as ultrasonic NDE measurement models. In other areas of engineering, models have revolutionized how engineering is practiced. A classic example is the impact of the finite-element method on elastic stress analysis.

Nondestructive evaluation (NDE) procedures are needed for materials processing, as well as for post-process materials testing. They play important roles in product design, analysis of service-life expectancy, manufacturing and quality control of manufactured products. They are also essential to on-line monitoring of the integrity of structural elements and complex systems. Rational accept and reject criteria should be based on NDE tests. Critical safety, efficiency and operational features of large-scale structures depend on adequate NDE capabilities. The lectures presented in this volume are concerned with quantitative ultrasonic NDE. They present fundamental concepts and basic theory, as well as applications to the detection of cracks and the evaluation of material properties. The following topics are discussed: basic wave propagation theory for ultrasonic NDE; piezoelectric transducers, EMATS and ultrasonic spectroscopy; laser-based ultrasonics; acoustoelasticity; ultrasound in solids with porosity, microcracking and polycrystalline structuring; the determination of mechanical properties of composite materials; inverse problems and imaging.

Most books on ultrasonic nondestructive evaluation (NDE) focus either on its theoretical background or on advanced applications. Furthermore, information on the most current applications, such as guided wave techniques and acoustic microscopy, is scattered throughout various conference proceedings and journals. No one book has integrated these aspects into a treatment that is both self-contained and up-to-date. Ultrasonic Nondestructive Evaluation: Engineering and Biological Material Characterization brings together the principles, equations, and applications of ultrasonic NDE, both traditional and state-of-the-art, in a single, authoritative resource. It begins with the relevant fundamentals of mechanics, derives the basic equations of the mechanics of elastic wave propagation, and then, step-by-step, covers the advanced topics and applications of ultrasonic NDE that are at the forefront of today's research. These include engineering, biological, and clinical applications, such as structural health monitoring, the characterization of biological cells, and real-time blood flow measurement. Written in plain language by some of the world's leading experts, the chapters are filled with case studies, worked examples, and exercises that help make this book an outstanding resource for course work, as well as for reference. If you are looking for that one book that can bring you quickly up-to-speed on the principles, technologies, and latest applications of ultrasonic NDE, look no further than this book.

Numerous works on non-destructive testing of food quality have been reported in the literature. Techniques such as Near InfraRed (NIR) spectroscopy, color and visual spectroscopy, electronic nose and tongue, computer vision (image analysis), ultrasound, x-ray, CT and magnetic resonance imaging are some of the most applied for that purpose and are described in this book. Aspects such as theory/basics of the techniques, practical applications (sampling, experimentation, data analysis) for evaluation of quality attributes of food and some recent works reported in literature are presented and discussed. This book is particularly interesting for new researchers in food quality and serves as an updated state-of-the-art report for those already familiar with the field.

During the last decade, the emergence of ultrasonic techniques for nondestructive evaluation of materials has provided a strong impetus for the study of propagation and diffraction of elastic waves. Elastic wave propagation studies have led to quantitative techniques for evaluation and service-life prediction of structures. The IUTAM Symposium provided an opportunity for researchers active in the interdisciplinary field of QNDE to assess progress and delineate areas of future research. Leading researchers presented state-of-the-art lectures, focusing attention on an important technological area in which wave propagation studies have made, and will continue to make important contributions toward advancing the technology. The volume provides a comprehensive overview on the current state of analytical, numerical, and experimental techniques as well as outlining future research needs. It provides evidence of important advances that have been made in the detailed analysis and experimental verification of ultrasonic scattering by single and multiple defects in isotropic medium. Judging by the progress made in the last decade, it is anticipated that ultrasonic techniques will find more and more use in quantitative nondestructive evaluation. In that regard it is hoped that this volume will be a valuable reference to researchers and practitioners in ultrasonic NDE. A selection of contents: A.
