Paper Abstract

The paper demonstrates application of nonlinear acoustics for crack detection in a glass plate. FE analysis is performed to establish structural resonances of the glass plate. Simulation analysis and experimental tests are used to select ultrasonic frequencies. Finally, nonlinear acoustic tests are performed to detect cracks. A high-frequency ultrasonic signal is introduced to the glass plate. At the same time the plate is modally excited using selected resonance frequencies. Surface-bonded, low-profile piezoceramic transducers are used for low- and high-frequency excitation. The experiments lead to vibro-acoustic wave modulations. The presence of modulation indicates damage and the intensity of modulation describes its severity.
