Abstract

This research investigates excitation and detection of guided wave modes for quantitative evaluation of a flaw in a thin metallic rod by using electromagnetic acoustic transducers (EMATs). Various modes can be excited by optimizing configurations of an EMAT and adjusting the frequency of input current. We simulated excitation of flexural modes F(1, m) by numerical analyses. Excitation of these modes was also examined experimentally. Temporal frequency analyses of receiver signals showed F(1,3) was successfully excited by EMAT.
