• Abstract:
  In August 1985, the FRA Associate Administrator for Safety asked the DOT Transportation Systems Center to make a preliminary technical assessment of the adequacy of the manufacturer's inspection and repair procedures. The Center formed a task force for this purpose, consisting of five senior engineering faculty members from three universities, a National Bureau of Standards expert on tank car steels, and two senior members of the Center's technical staff. The task force members are nationally recognized authorities on structures, structural fatigue, and fracture mechanics. This report summarizes the task force assessment of the inspection and repair procedures. The task force has identified two major technical issues: adequacy of crack detection; and ability to repair detected cracks without collateral damage.
