Effect of Protective Coating Thickness on Ultrasonic Guided Wave Propagation in Plate‐Like Structures

Macromolecular Symposia, EarlyView.
ABSTRACT Ultrasonic Guided Waves (UGWs) are widely employed for the inspection and monitoring of plate‐like structures due to their long‐range propagation capability and sensitivity to structural and material changes. In real aerospace components, however, structural surfaces are commonly covered by protective layers, such as coatings or metallic films,
