Predicting Response of Munitions to Massive Secondary Fragment Impact a Proposed Analytical Method

Abstract : This paper presents an analytic method for studying the mechanisms that lead to the detonation of cased munitions filled with molten explosives when impacted by large concrete fragments, representing failed wall sections. This is a single degree of freedom dynamic structural analysis method which makes use of predetermined, nonlinear load-deflection characteristics of the shell casing. In the analysis described, the method was applied to predict the pressure-time history in the molten explosive comparison between analytical and experimental results was obtained.
