A study of the vibro-acoustic modulation technique for the detection of cracks in metals
TL;DR: In this article, the sensitivity of the vibro-modulation technique is investigated systematically on a set of mild steel beams with cracks of different sizes and shapes A damage index was measured for each crack The correlation obtained between the crack size and the strength of the modulation is fairly poor.

Impact damage detection in laminated composites by non-linear vibro-acoustic wave modulations
TL;DR: In this article, a low-velocity impact was used to damage one of the composite laminates, and an ultrasonic C-scan was applied to reveal the extent of barely visible impact damage.

Ultrasonics of non-linear contacts: propagation, reflection and NDE-applications
TL;DR: The results of experimental investigation of acoustic non-linear phenomena on contact boundaries are presented in this article, where simulation experiments demonstrated a threshold nonlinear distortion due to "clapping" and "kissing" mechanisms, multiple bifurcations and chaos development for contact vibrations.
