Monitoring the Evolution of Fatigue Damage for Composite Using Guided Waves

Tang, J. F. / Lu, X. / Yan, G.

Abstract This paper presents a preliminary experimental study on detecting and monitoring of fatigue damage for composite under cyclic loads using guided waves. A glass fiber reinforce polymer (GFRP) composite laminate with PZT transducers on its surface is fatigued under tension-tension loads. At different fatigue cycles, one PZT transducer acts as actuator to excite diagnostic guided waves into the GFRP laminate and the other acts as sensor to receive corresponding response waves. These guided wave signals are then processed by wavelet packet transform (WPT) to extract characteristic feature and calculate damage indices to reflect the accumulated internal fatigue damage. Experimental results have demonstrated the potential applicability and effectiveness of guided waves for continuous monitoring of fatigue damage in composite structure.
