The book sets the stage for nonlinear ultrasonic guided waves by introducing nonlinear wave propagation in 1D and the fundamental mathematical and continuum mechanics background necessary for the nonlinear wave propagation physics. It develops the so-called internal resonance criteria and its application to different guided wave types. An important and unique aspect covered is the selection of primary wave modes and frequencies for cumulative second harmonic generation and wave mixing. Numerical simulations will demonstrate the results of effective selection choices. Experimental methods and signal processing are critical for detecting the subtle results of nonlinearity. Finally, the author provides perspective on the future development of nonlinear ultrasonic guided wave methods for nondestructive evaluation.

Researchers and practitioners in the nondestructive evaluation and condition monitoring communities that service mechanical equipment, ground/water/air/space vehicles, power generation and distribution systems, civil infrastructure, and manufacturing.

Cliff Lissenden is a professor of engineering science and mechanics at Penn State. He joined the Department of Engineering Science and Mechanics in 1995 and gained a joint appointment in Acoustics in 2011. He is an ASME Fellow and the founding director of the Ben Franklin Center of Excellence in Structural Health Monitoring. His current research is mainly for nondestructive characterization of materials using ultrasonic guided waves and is broadly applicable to metals, composites, concrete, rock, and bone. Characterization systems use piezoelectric, magnetostrictive, electromagnetic, and laser-based transduction of ultrasonic waves for nondestructive testing, inspection, and monitoring, often in harsh environments.
