A Novel Method for Ultrasonic Evaluation of Horizontal Defects Using Time-of-Flight Diffraction

Time-of-flight diffraction method (ToFD) is an amplitude-independent sizing method which is based on the measurement of time-of-flight of defect tip diffracted waves. Although ToFD can measure through-wall length of defect accurately, this method is not capable of measuring horizontal defect size. I...
