Damage Identification Based on Lamb Waves
1. A quantitative expression of anisotropic wave front was proposed to reveal the direction dependency of Lamb wave propagation in composite laminates;
2. On basis of the wave-front equation, a reliable and efficient detection approach for damage localization in composite laminates was developed;
3. Proposed a detection method to quantitatively identify the interface and size of a delamination, even though the delamination interface was not pre-given.
