Puncture of shielded radioactive material shipping containers: analysis and results. Final technical report
The development of improved analytical methods for predicting puncture of radioactive material shipping containers is reported. 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.
