An Ultrasonic Guided Wave Mode Selection and Excitation Method in Rail Defect Detection
Different guided wave mode has different sensitivity to the defects of rail head, rail web and rail base in the detection of rail defects using ultrasonic guided wave. A novel guided wave mode selection and excitation method is proposed, which is effective for detection and positioning of the three...
