Stub Penetration in Chemical Munition Shipment
Abstract
The M55 warhead carries a chemical agent which must be protected from accidental puncture in a shipment or handling accident. This report presents results from computer runs calculating the threshold impact velocity if a pallet of munitions or protective package containing several pallets were to be dropped onto rigid stubs of different radii. Calculations were made for three separate cases. Case 1 involved stub penetration of a fiberglass shipping container and then the aluminum walls of the round. Case 2 added an extra layer of protection so that wooden two by fours had to be penetrated before the shipping container and munition a CAMPACT shipping container loaded on a flat bed railroad car or highway vehicle. The computer code used to make all computation is a dynamic plasticity, multi-penetration stage, one just developed by SRI for the U. S. Army Tank Automotive Command. Some comparisons are presented in which this code predicts experimentally observed penetrations to demonstrate the validity of its use in this study.
