Guided wave inspection potential of defects in rail

Last updated on 02 September 2014 3:45

Experimental results are presented that suggest that frequencies in the range [40, 80] kHz readily support guided waves. Theoretical results that include dispersion curves for a rail and a sample of wave displacement within a railhead are presented. Non-contact air-coupled and electromagnetic acoustic transducers (EMATs) are discussed as receivers of...
