Abstract
This work presents acoustic emission (AE) waveform to source coordinates transformation at hollow cylinders facilitated by multiple Lamb mode arrivals due to the cylindrical geometry. Variational autoencoder (VAE) is selected to perform waveform source discrimination by capturing the delays in time-of-flights (TOF) between modes described in the transformation. An AE waveform dataset simulated by pencil lead break on a liquid nitrogen tank was collected to validate the proposed approach. The result indicates that VAE is capable of separate AE waveforms by their sources through the targeted delays between mode arrivals.
