Hyperbolic location damage imaging method based on ultrasonic Lamb wave

Hyperbolic location method based on ultrasonic Lamb wave is proposed in this paper, the damage location of composite plate structure is realized. Compared with ellipse location method, hyperbolic location method has the advantages of needing no material parameter information, no frequency dispersion relation and no influence of anisotropy. It can be better applied to damage detection of composite laminates.
