Axial Stress Measurement of Steel Tubes Using Ultrasonic Guided Waves
Sensors, 2022 Axially loaded steel tubes are widely used as primary structural members in civil engineering structures. In this paper, a stress measurement method for axially loaded steel tubes is developed based on the linear relationship between the group velocity ...

Effect of Pipe Bends on the Low-Frequency Torsional Guided Wave Propagation
Archives of Acoustics, 2020 Wave motion in pipe bends is much more complicated than that in straight pipes, thereby changing considerably the propagation characteristics of guided waves in pipes with bends.

Journal of Fluid MechanicsGuided-jet waves have been shown to close resonance loops in a myriad of problems such as screech and impingement tones in jets. These discrete, upstream-travelling waves have long been identified in linear-stability models of jet flows, but in this work they are instead considered in the context of an acoustic-scattering problem.

Open Guided Waves: online platform for ultrasonic guided wave measurements [PDF]
Structural Health Monitoring, 2018 Ultrasonic guided waves have been used successfully in structural health monitoring systems to detect damage in isotropic and composite materials with simple and complex geometry. A limitation of current research is given by a lack of freely available benchmark measurements to comparatively evaluate existing methods.

Guided Wave for plate inspection
e-Journal of Nondestructive TestingGuided wave ultrasonic testing (GWT) for plate inspection presents a valuable non-destructive evaluation technique for monitoring large, inaccessible structural components such as petrochemical tank floors and dam penstock gates. Unlike traditional spot-
