This work focuses on using Rayleigh waves to detect and characterize vertical, and oblique shaped surface breaking defects specifically caused by Rolling Contact Fatigue (RCF). The transmission coefficient (Tc) of Rayleigh wave was studied using finite element analysis (FEA). The results suggest that for oblique cracks, that characterization based purely on the Tc can be challenging due to fluctuations. This points to the need for additional parameters to be identified for efficient characterization of RCF.
