This extensively revised and updated second edition of a widely read classic presents the use of ultrasound in nondestructive evaluation (NDE) inspections. Retaining the first edition's use of wave propagation /scattering theory and linear system theory, this volume also adds significant new material including:

• the introduction of MATLAB® functions and scripts that evaluate key results involving beam propagation and scattering, flaw sizing, and the modeling of ultrasonic systems.

• elements of Gaussian beam theory and a multi-Gaussian ultrasonic beam model for bulk wave transducers.

• a new chapter on the connection between ultrasonic modeling and probability of detection (POD) and reliability models.

• new and improved derivations of ultrasonic measurement models.

• updated coverage of ultrasonic simulators that have been developed around the world.
  Students, engineers, and researchers workingin the ultrasonic NDE field will find a wealth of information on the modeling of ultrasonic inspections and the fundamental ultrasonic experiments that support those models in this new edition.

Describes the fundamentals of wave propagation needed to simulate the propagation and scattering of ultrasonic waves An updated and revised edition of a well-received classic New edition includes MATLAB functions and scripts that make the use of models more accessible to the reader End-of-chapter problems provide a deeper understanding of the material Includes supplementary material: sn.pub/extras

Les Schmerr received a B.S. degree in Aeronautics and Astronautics from the Massachusetts Institute of Technology in 1965 and a Ph.D. in Mechanics from the Illinois Institute of Technology in 1970. Since 1969 he has been at Iowa State University where he is currently Professor of Aerospace Engineering and Associate Director of the Center for Nondestructive Evaluation. He is also the Permanent Secretary of the World Federation of NDE Centers. His research interests include ultrasonics, elastic wave propagation and scattering, and artificial intelligence. He has developed and taught Ultrasonics and Nondestructive Evaluation courses at both the undergraduate and graduate level. He is the author of the book Fundamental of Ultrasonic Nondestructive Evaluation - A Modeling Approach which was published by Plenum Press in 1998 and the book Ultrasonic Nondestructive Evaluations Systems - Models and Measurements which was published by Springer in 2007. He is a member of IEEE, ASME, ASNT and AIAA.
