title = "A damage identification method using multimodal Lamb waves",
abstract = "The structure wall thinning always leads to changes in the frequency-thickness product, which alter the velocity of multimodal Lamb waves and affect the time of flight (TOF) of the wave packet. This paper presents a defect identification method using the TOF difference of multimodal Lamb waves to detect thickness thinning. By analyzing the TOF difference of at least two modes, the length and depth of defect can be determined. Numerical simulations show that this method can effectively identify defects caused by a cross-sectional area loss of with error about 5\% or less. It shows the reliability of the proposed method.",
