The Analysis on AE Signals During the First Boosting

During the acoustic emission(AE) testing it is often difficult for people to distinguish the noise and helpful AE signal because of the too many influence factors in the first boosting. Not enough attention was paid to AE signal of the first boosting in the current standard, but there was rich structure fault related information in the first boosting. The research is important for AE signal of the first boosting by the testing case.
