This article presents a comprehensive review of the laser-based guided ultrasonic waves
propagation imaging (G-UPI) system and respective signal/data processing methods related …

This paper describes the use of wavenumber filtering for damage detection with a signal-
frequency standing wave excitation on composite structures. Using a single, fixed frequency …

In this study, we propose an ultrasonic inspection technique for detecting disbonds in
adhesively bonded carbon fiber-reinforced plastics (CFRP)/aluminum joints using pulsed …

Abstract 3D-printed carbon fiber reinforced plastic (CFRP) composites have attracted
significant attention due to their design flexibility and low manufacturing cost. However, 3D …

Guided ultrasonic wavefield propagation imaging (GUPI) is useful for visualizing hidden
flaws in aerospace thin-walled structures, but the need for subjective signal processing …

Incipient thermal damage (ITD) in polymer-matrix composites could cause substantial loss of
material properties and it is notoriously difficult to be detected using nondestructive …

This study proposes a novel wireless guided-wave ultrasonic propagation imaging (GUPI)
system to enable completely wireless inspections of structures. A conventional GUPI system …

As the number of FCEV vehicles increases, the importance of safe hydrogen fuel storage
becomes larger. Hydrogen energy needs a high-pressure composite pressure vessel called …

Water ingress into the honeycomb cells of aerospace structures can compromise the
aircraft's safety and performance. Due to this reason, detecting it as soon as possible is …

Acoustic emission (AE) is a transient phenomenon in which an elastic wave propagates to a
structure as a result of structure damage such as micro-cracks, internal-cracks, friction, fiber …
