Abstract : The analysis of explosive detonation via projectile impact is inherently complex because of the many variables which must be considered. One very important variable is the nose or tip shape of the projectile which contacts the bare unprotected planar surface of the energetic material. This report demonstrates that Hemispherical Nose (HN) projectiles (cylindrical, rods, or spheres) are equivalent to a much smaller Flat Nose (FN) surface. This equivalence is suggested by comparison with appropriate theory and a very limited amount of experimental data for two explosives (PBX-9404 and COMP-B).
