Large Area Detection of Microstructural Defects with Multi-Mode Ultrasonic Signals
Applied Sciences, 2022 Cyclic loading or other stresses can lead to development of cracks and crack growth in mechanical structures, leading to eventual failure. While ultrasound imaging can be used for non-destructive testing of such structures, conventional ultrasound ...

High-Frequency Guided Ultrasonic Waves to Monitor Corrosion Thickness Loss [PDF]
, 2016 Corrosion due to adverse environmental conditions can occur for a range of industrial structures, e.g., ships and offshore oil platforms. Pitting corrosion and generalized corrosion can lead to the reduction of the strength and thus degradation of the ...

Shear horizontal (SH) ultrasound wave propagation around smooth corners [PDF]
, 2014 Shear horizontal (SH) ultrasound guided waves are being used in an increasing number of non-destructive testing (NDT) applications. One advantage SH waves have over some wave types, is their ability to propagate around curved surfaces with little energy ...

Deciphering acoustic emission signals in drought stressed branches: the missing link between source and sensor [PDF]
, 2015 When drought occurs in plants, acoustic emission (AE) signals can be detected, but the actual causes of these signals are still unknown. By analyzing the waveforms of the measured signals, it should, however, be possible to trace the characteristics of ...

A match coefficient approach for damage imaging in structural components by ultrasonic synthetic aperture focus [PDF]
, 2017 Ultrasonic Synthetic Aperture Focus (SAF) techniques are commonly used to image structural defects. In this paper, a variation of SAF based on ideas borrowed from Matched Field Processing (MFP) is evaluated to reduce artifacts and sidelobes of the ...
