Acoustic Emission Technology

It is vital to use acoustic emission technology to study on health monitoring of concrete. The aim of this study is to investigate the ability of the AE in order to test the effect of the stepwise displacement load on the damage mechanism of the concrete beams that embedded sensors under three-point bending. The result showed that as the damage increased, amplitude and energy increased. At the same time, embedded sensors can locate the position of the crack.
