Review of nonlinear ultrasonic guided wave nondestructive evaluation: theory, numerics, and experiments
Optical Engineering: The Journal of SPIE
Interest in using the higher harmonic generation of ultrasonic guided wave modes for nondestructive evaluation continues to grow tremendously as the understanding of nonlinear guided wave propagation has enabled further analysis. The combination of the attractive properties of guided waves with the attractive properties of higher harmonic generation provides a very unique potential for characterization of incipient damage, particularly in plate and shell structures. Guided waves can propagatedoi:10.1117/1.oe.55.1.011002 fatcat:yju7wuh6q5gmbawi2bcmczm3m4
