摘要：
In the whole crack growth process such as initiation, propagation, and final fracture, strong acoustic emission source may occur. Each time when the crack initiates or propagates, it may lead to acoustic emission events, so in engineering, acoustic emission testing technology can be used to test the cracks' propagation online. In this paper, acoustic emission testing technology is used to test the acoustic emission events under different load locations. The regularity between the times of acoustic emission and load cycles is researched via experiments to analyze the effecting laws between the load location's variation and crack propagation speed.
