This report describes a recent attempt to develop a test method for use in screening materials and for evaluating the effects of certain parameters, for example section stiffness, on container penetration resistance. In addition, it illustrates the application of this procedure to the selection of a sheet steel for a transuranic waste (TRUPACT) container. The test consists of penetrating a specimen, normally 0.6 m square, with a punch (tup) attached to a falling weight and recording and analyzing the force-time history to determine the energy absorption during the impact event. The test as developed simulates certain aspects of the 10CFR71 drop test in order to provide a means of comparing, for example, the penetrating resistance of various steels, this resistance being defined as the energy required to initiate fracture in the specimen. In summary, this examination suggests that it should be possible to develop a laboratory test to rank and select materials for maximum puncture resistance. Although the initial results appear promising, more effort will be required before this procedure can be routinely applied to examining the various factors which control the puncture resistance of these materials. These results do, nonetheless, show that high-strength, low-alloy steels do offer significant advantages over mild steel for container penetration protection. Indeed, one of these steels, NAX-80, is presently considered as a prime candidate for the TRUPACT container being developed at Sandia National Laboratories.
