This paper presents a new crack size quantification method based on in-situ Lamb wave
testing and Bayesian method. The proposed method uses coupon test to develop a baseline …

A damage localization method based on the time reversal focusing of the mode-converted
scattered Lamb wave is proposed for plate structures with a non-symmetric defect in the …

A Lamb wave-based, subwavelength imaging algorithm is developed for damage imaging in
a metallic plate based on a decomposition of the time-reversal operator method together …

The paper demonstrates how to remove the undesired temperature effect from Lamb wave
data in order to detect structural damage accurately. The method used is based on the …

Guided waves are increasingly being researched and applied for use in defect detection.
Because different guided wave mode conversions and noise are inevitably generated by …

A time–frequency signal processing procedure aimed at extending pulse-echo defect
detection methods based on guided waves to irregular waveguides is proposed. In …

A non-linear Lamb wave signal processing strategy aimed at extending the capability of
active–passive networks of PZT transducers for defect detection is proposed. In particular …

Ultrasound imaging using an active sensing array has been extensively studied in both time
domain and frequency domain. Subspace decomposition methods in match field …

Inspection of the elastic properties of plate-like structures is an important and challenging
problem in many engineering disciplines. There exist multiple non-destructive inspection …

This paper presents a non-contact ultrasonic method using Lamb waves, for the automatic
quality control of cellulose fibre cement boards during their production. The causes of typical …
