摘要：Nonlinear Lamb wave has been widely acknowledged as an efficient Nondestructive Testing (NDT) for detection early stage of fatigue damage. The previous studies focused on the evaluation of fatigue damage using the particular mode pairs, such as S1-S2 mode pair. Recently, Nonlinear S0 Lamb mode with low-frequency was considered for its unique features of less dispersion and easy to be generated, and was indicated may as sensitive to fatigue damage as other mode pairs reported before. However, few researches were performed on experimental measurement. In this work, the S0 mode is demonstrated as an alternative for fatigue damage detection. ? 2017 IEEE.
