Abstract
Guided waves are propagated in rods and pipes for a long distance without energy loss. Therefore, compared with conventional methods requiring long time, guided waves are ideal for non-destructive testing of wireropes. In this research, aiming to evaluate effects of the geometry of wireropes on guided wave propagation and to generate particular oscillation modes, we carried out experiments and finite element analysis. The results of experiments showed selective excitation of oscillation modes by electromagnetic acoustic transducers and propagation of guided waves along peripheral strands. Numerical results showed slight effect of helical structure on received signals.
