• Abstract:
  The Federal Railroad Administration of the U.S. Department of Transportation is concerned with the safety of the public and the crews clearing wrecked tank cars containing hazardous materials. To assess the safety of moving a damaged tank car, it is necessary to know the sizes and shapes of cracks, the stresses associated with moving the tank car, and the fracture toughness of the material used to fabricate the tank car. This report provides the results and recommendations for the following research related to the above needs: (1) examination of nondestructive evaluation techniques and measurements of the mechanical properties of deformed steel plate; (2) evaluation of computer codes to identify those capable of performing a large displacement inelastic analysis; (3) two 1/5-scale-model tank cars, representing damaged tank cars, were hydroburst to failure; and (4) preliminary tests were conducted using moire interferometry for determining residual stresses of rail components.
