Abstract

Nonlinear Lamb wave mixing provides a potential method to assess the localized material degradation in plate-like structures. The sum harmonics generated by the nonlinear mixing of counter-propagation Lamb waves under internal resonance criteria were acquired through scanning an aluminum alloy plate with localized micro-damage and closed crack in finite element simulations and experimental measurements, respectively. Both results illustrate the capability of the nonlinear interaction of counter-propagating Lamb waves to detect localized micro-damage.
