Abstract :
The paper describes a structural health monitoring concept based on the evaluation of acoustic Lamb waves. Using a suitable damage indicator like the correlation coefficient it is possible to detect and localize defects in the observed structure. The functional capability was shown in statical test of a part of a rotor blade.
