Study of Fragmentation Dispersion Measurements of Unique Multilayer Fragmenting Structure

摘要

This program was carried out to demonstrate the feasibility of this unique multilayer fragmenting structural concept. The demonstration was planned as an experimental and analytical program. The mechanical properties predicted by the analytical model were to be compared with the measurement of these properties. The experimental results would be used to establish the feasibility. In order to accomplish a lower cost development the early tests were to be carried out using substitute or surrogate materials. The surrogate materials development program provided low cost guidance for the tooling design and casting approaches for the final steel castings. When the surrogate manufacturing processes and procedures were evaluated and the surrogate composite properties measured, the final high temperature investment casting development efforts and property measurements would be accomplished using a high strength castable stainless steel. Casting and characterizing the steel flat plate concepts demonstrated the good structural properties of the integrated fragmenting warhead concept and provided the need to proceed to the cylindrical test program.
