Ultrasonics

Updated, revised and restructured, to reflect the latest advances in science and applications, the Fourth Edition of this best-selling industry and research reference covers the fundamental physical acoustics for ultrasonics, transducers, with a focus on piezoelectric and magnetostrictive modalities. It then discusses the full breadth of ultrasonics applications involving low-power (sensing) and high-power (processing) for research, industrial and medical use. The book includes new content covering computer modelling used for acoustic and elastic waves phenomena, including scattering, mode-conversion, transmission through layered media, Rayleigh and Lamb waves and flexural plates, modern horn design tools, Langevin transducers, and material characterization. There is more attention on process monitoring, advanced NDT/NDE, including phased arrays (PAUT), long-range ultrasonics, using guided waves (GUW), internally rotating systems (IRIS), time-of-flight diffraction (TOFD) and acoustic emission (AE). These methods are discussed applied to both metals and non-metals, using illustrations in various industries, including for food and beverage products. The topics of defect sizing, capabilities and limitations, including probability of detection (POD), are introduced. Three chapters provide a new treatment of high-power ultrasonics, for both fluids and solids, and again, with industrial engineering, food and beverage, pharmaceuticals, petrochemical and other process applications. Expanded coverage is given to medical and biological applications, covering diagnostics, therapy and, at the highest powers, surgery.

x Provides an overview of fundamental analysis and transducer technologies needed to design and develop both measurement and processing systems.

x Considers applications in material characterization and metrology.

x Covers ultrasonic nondestructive testing and evaluation and high-power ultrasonics, which involves interactions that change the state of material

x Highlights medical and biomedical applications of ultrasound, focusing on the physical acoustics and the technology employed for diagnosis, therapy, surgery, and research.

This book is intended for both the undergraduate and graduate scientist and engineer, as well as the working professional, who seeks to understand the fundamentals, together with a holistic treatment of the field of ultrasonics and its diversity of applications.
