Abstract
Propagation behaviors of the T(0,1) mode guided waves at a non-axisymmetric defect is investigated. The mode conversion from the T(0,1) fundamental torsional mode to the circumferential (C-) SH_0 mode at the defect was confirmed by the FEM simulation and the experiments along with the theoretical calculations. If the resonant conditions of C-SH0 mode waves predicted by the theory are satisfied, the large amplitude standing wave was observed in both FEM simulations and experimental results.
