Rayleigh echo
WebUltrasonic Rayleigh waves can be employed for the detection of surface breaking defects such as rolling contact fatigue and stress corrosion cracking. Electromagnetic Acoustic Transducers (EMATs) are well suited to this technique as they can directly generate Rayleigh waves within the sample without the requirement for wedges, and they are … WebJan 1, 2015 · 4. Conclusions Ultrasonic waves propagating along ground surface is measured, and the result of velocity analysis shows that a Rayleigh wave with high …
