Development of a method for estimating the time-of-arrival of acoustic emission signals for structural health monitoring

International Journal of Structural Integrity
This study aims to develop a novel method for estimating the time-of-arrival (ToA) of acoustic emission (AE) signals generated by materials under loading. To use the estimated ToA to analyse damage evolution in the material. The ToA estimation
