In this paper, some recent piezoelectric wafer active sensors (PWAS) progress achieved in
our laboratory for active materials and smart structures (LAMSS) at the University of South …

Damage is an inevitable occurrence in metallic structures and when unchecked could result
in a catastrophic breakdown of structural assets. Non-destructive evaluation (NDE) is …

The significance of evaluating bolt tightness in engineering structures, preferably in a
continuous manner, cannot be overemphasized. With hybrid use of high-order harmonics …

The aim of this research is an analysis of full wavefield Lamb wave interaction with impact-
induced damage at various impact energies in order to find out the limitation of the …

This research is related to a detection and imaging method of delamination damage in
CFRP composite laminate structures. Conventional guided wave detection methods often …

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 novel full wavefield processing method by using fully convolutional neural networks is
presented. The full wavefield of propagating Lamb waves in the fibre-reinforced composite …

Herein, we developed a nonlinear ultrasonic three-wave mixing technique to more
accurately detect and localize early-stage fatigue cracks. First, we derived the theoretical …

Guided wavefield analysis methods for detection and quantification of crack damage in an
aluminum plate are presented in this paper. New wavenumber components created by …

The surface rolling contact fatigue crack is a common crack on the rail surface. When it
extends to a certain length, it will lead to rail fracture and affect the safety of railway …
