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 …

Thin-walled structures, like aircraft skins and ship shells, are often several meters in size but
only a few millimeters thick. By utilizing the laser ultrasonic Lamb wave detection method …

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 …

Hidden corrosion damage of aircraft structures is a potential threat to the flight safety and a
major maintenance factor for aircraft. In previous researches on corrosion detection, the …

Lamb wave phased arrays employ sensors placed close to each other in compact
distributions and can quickly inspect large plate-like structures through time (or phase) …

Air-coupled ultrasonic testing and C-scan technique has been increasingly applied to the
braided CFRP structures owing to its non-destruction, non-contact and high visualization …

In this paper application of scanning laser Doppler vibrometry for delamination detection in
composite structures was presented. Delamination detection was based on a guided wave …
