Ultrasonic guided waves are now routinely used in non-destructive evaluation. In plate-like structures, three fundamental modes can propagate, namely A0, S0 and SH0. Most of the guided wave literature has thus far focused on the use of A0 and/or S0 because these modes are easy to generate in plate-like structures using standard piezoceramic transducers. Yet, at low frequency, A0 and S0 are dispersive. The consequence of dispersion is that signal processing becomes complex for long propagation distances. SH0, on the other hand, has the particularity of being the only non-dispersive guided wave mode. Omnidirectional transduction of SH0 requires a rotational surface stress which cannot be easily generated using standard piezoceramic transducers. This project investigated the use of piezoceramic shear plates cut into six trapezoids bonded to a plate in order to form a discretized circle. The individual elements of the hexagonal shaped transducer were synchronized to generate shear surface stress simultaneousl...
