Descripció: In current work, Andrew plot is used as a new index to detect any probable damage in the structure. At the first step, using piezoelectric actuators and sensors, appropriate lamb wave is propagated and received through the structure. Then Principal Component Analysis is applied to the recorded data and prepares necessary data for Andrew curves. Andrew plots are depicted based on calculated principal components. It has been shown that comparing Andrew curves from baseline, structure without damage, with current statues of structure can identify any probable damages in the structure.
