Analysis on Defects Location during Rebar Pull-Out Test by Acoustic Emission Technique

Abstract:

To confirm precision of acoustic emission source localization technique and validate rationality of acoustic emission parameters setting in concrete detection, defects location in pull-out specimens during bond failure were monitored by the method of 3D localization technique. In the monitoring,formation and propagation of cracks calculated by localization algorithm agrees with the real situation. AE parameters proposed in the paper help to identify source location with high accuracy.
