Description
Siyang Xie, Youxuan Zhao, and Yuzi Liu test a wave-mixing method for finding damage in composite panels. Their 2025 paper mixes Lamb waves with shear horizontal waves one way. When the two waves cross in a damaged zone, a resonant wave appears. That echo can betray hidden flaws without cutting the panel.
Panels carried built-in nonlinearity, delamination, and impact damage. The resonant signal rose as theory required when waves met in damage. Timing of the echo located the damage spot. The method sensed natural nonlinearity and impact harm clearly. Delamination, though, barely registered. Knowing a tool's blind spots is part of trusting it. This one sees some wounds sharply and others hardly at all.
