The Acoustic Emission Monitoring During the Bending Test of Q235 Steel Box Beam
Acoustic emission characteristics of the Q235 steel box beam with external crack are monitored during the bending test. The AE parametric characteristics and location characteristics of the crack propagation in the test are discussed. The AE intensity and gross in the elastic deformation section are less than the section after yield deformation. The maximum amplitude is 64dB in elastic deformation section. The defect can hardly be located when the box beam is loaded less than the maximum load of it with external crack during the elastic deformation section. The results indicate that the linear location method can be used well for the AE sources location of box beam when the external crack was propagated during the three-point bending test.
