Theoretical Analysis and Experimental Study on Acoustic Emission Wave Propagation in Perforated Thin-Walled Plate

摘要：

　　Through complex variables function,wave propagation of perforated thin-walled platesis deduced.And it is found out that the dynamical stress concentrates where the concentrationparameter vertical to incident orientation is about 1.5,and with the increase of incident wavefrequency,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 testof acoustic emission.
