Damage Identification Research for Steel Plate Based on Lamb Wave

摘要：

　　According to the characteristics of wave propagation in steel plate,choosing the suitable excite mode and frequency.Based on the wave structure of A0、S0,obtaining its displacement discipline,then arriving at the sensitivity effect for different depth of defect in different frequency.Making different depth circular damage in the steel plate,calculating the law of lamb wave in different damage by using continuous wavelet transform.
