In this paper, the influence of a gap on a plate on propagating acoustic emission waves is investigated. The existence of the gap on the plate remarkably affects the propagation of the acoustic emission waves whose source is near the tip of the gap. This effect of the gap cart be used to develop a tracking control system.
