. There are penetrating cracks on the surface of the rock specimen, and no fragments separated from the specimen during the failure process. Moreover, there is no sound when the specimen is destroyed......
into the furnace and melted. The melt was degassed by carbon hexachloride at 1023 K, and stirred to obtain uniform mixing. The slag on the melt surface was removed to avoid the formation of porosity or void during......
the collapse first occurred in the vicinity of impact surface at comparatively high velocities (~500 m/s). Further- more, the pore collapse mechanism was found to be governed by the shock propagation......
