2018 journal article

Multi-mode reverse time migration damage imaging using ultrasonic guided waves

ULTRASONICS, 94, 319–331.

By: J. He n, C. Leckey*, P. Leser* & W. Leser*

author keywords: Multi-mode; Guided waves; Damage imaging; Reverse-time migration; Elastodynamic finite integration technique
TL;DR: A reverse‐time migration imaging algorithm was combined with a numerical simulator—the three‐dimensional (3D) elastodynamic finite integration technique (EFIT)—to provide multi‐mode damage imaging that enables characterization of damage type and size, general sensitivity to unknown damage types, higher resolution imaging, and detectability regardless of the data acquisition system used.
