ABSTRACT
AET (acoustic emission tomography)
is a new visualization location method for inspecting and locating the internal
damages in the structures. In this paper, the AET is applied to detect and visualize
damage source locations in the Q235B steel structure to validate its effectiveness.
Firstly, the ABAQUS/Explicit simulation model of the steel structure with one damaged
circle in its center is built. And then, the simulated AE signals are obtained to
establish the AE tomography. The results show that the damaged circle in the created
model can be visualized clearly with the AET in its original location. Finally,
the damage source location based on AET is compared with the traditional TOA (time
of arrival) location method, and the better location accuracy is obtained. And this
fact that further illustrates the AET has a great potential in the application of
structure damage detection.
