Weakening Detection of Composite Structure Adhesive Layer Based on Nonlinear Guided Waves

Weakening Detection of Composite Structure Adhesive Layer Based on Nonlinear Guided Waves

In this study, a detection method utilizing nonlinear ultrasonic guided waves is presented to tackle the difficulties in detecting localized damage and weakening in bonded composite structures. For a three-layer structure made of polystyrene, acrylic resin, and aluminum plate, dispersion equations f...
