A concept for the identification and localization of delamination damages in CFRP is introduced. The general methodology is lined out and a localization method based on damage-caused modal damping variations is described. Using only scalar damping values requires a correlation of measured data to the corresponding data from a mathematical model in order to gain information on the damage location. The feasibility of the proposed concept is tested in an analytical damage simulation study on a stringer-stiffened aircraft panel. Some intermediate results are presented, including the modelization of piezoelectric elements and delamination damages, the selection of actuator and sensor positions and an analytical damage simulation. The work is part of the Advanced Aircraft Structures-Project (FFS) carried out by DLR in cooperation with DaimlerChrysler Aerospace.
