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 research related to the examination of nondestructive evaluation techniques and measurements of the mechanical properties of deformed steel plate; Evaluation of computer codes to identify those capable of performing a large displacement inelastic analysis; Two 1/5-scale-model tank cars, representing damaged tank cars that were hydroburst to failure; and Preliminary tests conducted using more interferometry for determining residual stresses of rail components. 24 refs., 37 figs., 4 tabs.
