EXPERIMENTAL STUDY ON DAMAGE DIAGNOSIS OF CONCRETE INTERIOR DEFECTS WITH ACOUSTIC EMISSION

The acoustic emission technology is one kind of dynamic non-destructive inspection technology,moreover sound transmitting message from flaw itself,therefore,may judge the flaw with the sonar efflux the gravity.A similar size, uniform quality flaw,when they receive the stress condition and locates when the position is different,is also different to the structure extent of damage,therefore their acoustic emission characteristic also has the difference.
