• Abstract:
  An approach to detecting and characterizing internal defects in rail through the use of phased array ultrasonic testing has shown the potential to reduce the risk of missed defects and improve transverse defect characterization. ; Transportation Technology Center, Inc. (TTCI) conducted research and data collection on rail flaw sizing and master gauge development using conventional and phased array ultrasonic testing techniques. This Federal Railroad Administration (FRA) research effort addresses both safety and reliability through the development of the Rail Flaw Library of Associated Defects (RF-LOAD) (Figure 1), which provides a test bed for performing probability of detection (POD) studies on commercially available nondestructive evaluation (NDE) systems, as well as NDE systems that are under development.
