Design of Radioactive Material Shipping Packaging for Low-Velocity Puncture Resistance
Both the standards developed by the International Atomic Energy Agency (IAEA) and those contained in the U. S. federal regulations  stipulate that transport packagings containing large quantities of radioactive material, such as spent fuel from a nuclear power reactor or waste by-products from nuclear weapons programs, should be designed to resist a sequence of impact, puncture, fire, and water immersion conditions without harmful release of contents. A recent paper  has offered a perspective on the design of such packagings relative to the impact event - a 30-foot (9 m) drop onto an essentially unyielding target. In that paper, it was shown that modern tools of computational mechanics, incorporating elastic-plastic material response and finite strain kinematic descriptions, could be used efficiently for the iterative design of a monolithic steel containment system, including models for bolted closures, shear keys, and seals.
