Thomas R. Hay received his BEng from Concordia University in mechanical engineering in 1998 and is currently a PhD candidate in engineering mechanics at Pennsylvania State University. His current research is funded by the Office of Naval Research. Since joining Pennsylvania State’s Ultrasonic Non-destructive Evaluation Center he has received the American Society for Non-destructive Testing Fellowship (2000), the National Science and Engineering Research Council of Canada Fellowship (2001–2003), and the Gordon M. MacNabb Scholarship for intelligent systems (2001). His interests include integrating ultrasonic guided wave technology with condition-based maintenance applications.

N2 - Flexible PVDF pipe comb transducers are easy to install by wrapping around any size pipe. It is possible to mechanically couple these transducers to the pipe thereby eliminating the need to bond electrodes to the film and adhesively couple the transducer to the pipe. The simple fabrication process, installation, and affordability of these transducers makes them realistic candidates for condition-based monitoring of some critical pipeline applications. These transducers are capable of exciting lower order axisymmetric modes with minimal radial displacement and maximum axial displacement as well as modes with both surface displacement components. This versatility is extremely important since under certain loading conditions, modes with significant radial displacement are almost completely attenuated.
