Abstract
Electromagnetic acoustic transducers (EMATs) have been used in pitch-catch mode for a better characterization of surface cracks in metals. The system, which combines the measurement of Rayleigh wave velocity in the in-plane and out-of-plane directions, has been used to understand the interaction of Rayleigh waves with inclined surface cracks. This shows a stronger and more prominent enhancement pattern when compared to the enhancement caused by cracks which are normal to the surface. In addition, measurements in the far-field are combined with the near-field enhancement measurement, with a view to characterize the cracks. An algorithm for characterizing surface cracks is presented. A finite element method model has been computed to simulate the experiment, and the cause of the prominent enhancement in the inclined cracks is explained.
