IMPACT VULNERABILITY OF TANK CAR HEADS
An Impact Vulnerability study of tank car heads was undertaken by means of semi-analytical evaluation of head failures through careful observation of indentations and punctures produced in a series of full scale tests. Vulnerability influencing parameters were identified. Simple formulas to determine the permanent indentation and the impact force were developed in conjunction with a theoretical analysis of influential dimensionless parameters and an application of Hertz' force-indentation law to collision problems. Finally, the tank car head failure criteria were established.
