Abstract : Impact forces from hardened, concrete targets to a General Purpose Warhead (bomb) can in some cases cause outer-case failure and breakup of the high explosive (HE) filler prior to fuse initiation. The detonation that is expected to occur under reliable penetration and for totally confined conditions can be reduced to that of a rapid deflagration with reduced damaged to the target/structure. This paper presents the solution to the dynamic equations of motion for gas-particle systems that simulate in one-dimension, the high pressure, subdetonation speed reactions in such beds of fragmented high explosive. It is clear from the results presented that initiation of a damaged, fragmented explosive will not necessarily result in a strong detonation if the mass and momentum losses from side vents (caused by the impact) are sufficiently large.
