In the aerospace industry,the non-destructive evaluation(NDE)techniques have been more and more important by concerning about more and more aircraft accidents.Compared to the conventional damage detection methods,the approach based on Lamb wave is an effective NDE technique to locate the damage position for its long distance detecting and low attenuation.However,it is too complicated to achieve a real-time monitoring directly and to estimate the damage size accurately for Lamb wave multi-modes and dispersion.
