A 3-D model of a 1.22 m ×1.22 m × 1.27 cm steel plate located vertically with respect to the ground plane is subjected to an explosive blast due to 0.9 kg spherical charge located 0.61 m above ground at 1.52 m standoff. The explosive was allowed to detonate and the resulting blast wave propagated through air until it reached the front surface of the plate. The reflected pressure-time history plot at the center of the plate up to 3 ms was compared with the experimental data. Peak pressure magnitude and time of occurrence between computation and experiment correlated satisfactorily. However, the secondary reflected peak magnitude and occurrence time did not match closely between computation and experiment. For impulse driven problems, such a difference would not be critical since total impulse and peak pressures between prediction and experiment agreed quite well.
