Puncture of shielded radioactive material shipping containers: static and dynamic tests of laminated plates
The report describes the development of improved analytical methods for predicting puncture of radioactive material shipping containers. 59 static and dynamic puncture tests of lead-backed, uranium-backed, and unbacked flat, circular, stainless steel plates with several mild-steel punch configurations were conducted. It was found that analytical puncture prediction requires two essential elements: (1) a code that will accurately track stress and displacement throughout the event and (2) a criterion for identifying when and if puncture occurs. (The puncture event is not self-evident from the calculation.) The NIKE2D finite element code was coupled with the puncture criteria--a shear stress criterion for the lead-backed plates and a maximum effective plastic strain criterion for the uranium-backed plates; the results agreed very well with the test data.
