Abstract : Two hydrocode packages, ALE3D and CTH, were used to model the blast from a 450-g sphere of the near-ideal explosive composition 4. The pressure profile was optically measured using high-speed video and streak camera imaging techniques. Pressure profiles were obtained by measuring the velocity of the shock wave and using the Rankine-Hugoniot theory to calculate peak pressure. The high-resolution model results were compared to the optical data, standard gauge data, and the empirical blast estimation code CONWEP.
