WebThis process is most easily discussed in terms of a frequency pulling induced on the Stokes wave optical frequency when the pump frequency is tuned (Debut et al., 2000). The … WebDec 5, 2024 · Early detection of defects inside a rail is of great significance to ensure the safety of rail transit. This work investigated the ability of ultrasonic guided waves (UGWs) to detect internal defects in a rail head. First, the model of UGW propagation in rail, which has an irregular cross-section, was constructed based on the semi-analytical finite element …
