Profiles of a peak pressure and b particle velocity along the central axis and the target surface, respectively, for the results shown in Fig. 7. The peak pressure profiles for 1031-3 (the closed tube impact at open side) and 0925-1 (open tube) are similar and hence almost overlap. The experimental results of crater depth and crater radius are indicated as vertical lines (the line and profile with the same color are corresponding)
