Abstract: By analyzing the damage characteristics of composite hat-stiffened panels, piezoelectric-based guided wave
monitoring technology was introduced into the damage monitoring of hat-stiffened panels. Finite element simulation was
firstly conducted on the propagation mechanism of guided waves in hat shaped reinforcement structure. The simulation
results showed that the propagation of guided waves in the hat-shaped reinforcement exhibited a complex characteristic of
first separation and then convergence with the structural form. In order to quantify guided wave signals, two damage index
algorithms with energy and correlation as measurement criteria were proposed. Finally, the piezoelectric-based guided
wave technology with two damage index algorithms was applied to the fatigue testing of composite hat-stiffened panels.
Experimental results showed that the propagation of lamination damage could cause significant signal changes of guided
waves. The energy damage index and correlation damage index algorithms could identify the propagation of lamination
damage on the hat-stiffened reinforcement. Although hat-stiffened reinforcement increased the complexity of guided wave
propagation, piezoelectric-based guided wave technology was still effective for monitoring the damage of reinforcement
bars in composite hat-stiffened panels.
