Testing of Permanently Installed Piezoelectric Ultrasonic Guided Wave Transducers for Structural Health Monitoring

Available to Purchase

Philip W. Loveday, Paul Fromme
Proc. ASME. QNDE2024, 2024 51st Annual Review of Progress in Quantitative Nondestructive Evaluation, V001T05A003, July 21–24, 2024
Publisher: American Society of Mechanical Engineers
Paper No: QNDE2024-138051
https://doi.org/10.1115/QNDE2024-138051
... Abstract Guided wave ultrasound can propagate large distances and enables the use of permanently installed piezoelectric transducers in structural health monitoring systems. The transducers can be exposed to harsh operating and environmental conditions, and it is advantageous to have a method...

Numerical Analysis of Guided Wave Transmission Through a Rail Containing Numerous Small Cracks

Available to Purchase

Philip W. Loveday
Proc. ASME. QNDE2022, 2022 49th Annual Review of Progress in Quantitative Nondestructive Evaluation, V001T03A006, July 25–27, 2022
Publisher: American Society of Mechanical Engineers
Paper No: QNDE2022-98277
https://doi.org/10.1115/QNDE2022-98277
... Abstract Guided wave ultrasound is used to monitor continuously welded rail track in a system which transmits guided wave ultrasound between alternate transmit and receive stations along the rail and triggers an alarm if the signal is not received. During field testing, a section of rail...
