| 内容記述 | The spall velocities produced by nine experimental impacts of 1 to 6.5 km/sec into San Marcos gabbro targets, using projectiles of Fe, Al, Pb, and basalt of various sizes, have been measured in conjunction with fragment-velocity high-speed filmings of the events. A detailed comparison is made between measured spall velocities and those predicted by the model of Melosh (1984), with a view to the compatibility of small-scale results and large planetary impacts. Attention is also given to the patterns of internal fracture generated by impact within the targets. |
