【 摘 要 】

In an earlier report, we presented results of modeling calculations for one simple geometry that represents an experiment potentially to be performed at Sandia National Laboratory, which is examining equation of state issues of interest to the National Missile Defense Program. In the earlier report, we showed snapshots of calculations with two different initial zone dimensions for Gruneisen EOS and LEOS. We also showed pressure profiles at various locations in a witness plate out of the way of direct projectile impact, but hit by shrapnel generated during impact. It was found that the pressure profiles exhibit strong dependence on location, zone size, and equation of state. In this report we examine the overall momentum impacted to the witness plate. This momentum shows negligible dependence on the equation of state and some dependence on zone size.
