Computer simulations of several hypervelocity impact events using the multi-dimensional, multi-material CTH shock wave physics code are presented and discussed. First, some two-dimensional CTH calculations are presented. These are then compared with calculations using another Eulerian shock wave physics code (CSQ) and with flash x-ray photographs of the impact events. Fully three-dimensional computations, including simulations of oblique impacts, will then be presented. Possible improvements in the physical and computational models used in the calculations will be mentioned. The influence of these calculations on CTH development will be discussed.
