WebFor Lamb wave-based damage detection approaches, the analysis is normally concentrated on a certain wave packet within the sensed guided wave signals. Based on the dispersive property of the guided wave propagation, the wave packet for analysis is typically correspondent to the S 0 or A 0 mode of the guided wave (Nasrollahi et al., 2024). WebJan 8, 2024 · The wavelet packet analysis method is utilized to analyze the transmitted signal between PZT patches through the steel strand anchorage system. Compared with the wavelet packet energy of received signals under different PZT combinations, it could be found that the wavelet packet energy increased with the increasing of anchorage system …
