Through complex variables function, wave propagation of perforated thin-walled plates is deduced. And it is found out that the dynamical stress concentrates where the concentration parameter vertical to incident orientation is about 1.5, and with the increase of incident wave frequency, holes have less influence on the dynamical stress concentration during wave propagation. With the help of acoustic emission technique, holes do not have much effect on nondestructive test of acoustic emission.
