内容記述 | Impact experiments on sintered snow were conducted at the impact velocities from 35 to 150 m/s. Snow and ice projectiles were launched into the snow target sintered at - 10 C for 15 minutes and at - 7 C for 45 minutes. The projectile and target porosity were about 32 and 36 percent respectively. The crater morphology depends on the projectile type and the degree of sintering of the target. The typical crater shape made by snow projectile is bowl shape with the depth to diameter ratio of about 0.5. The power law index of the impact velocity in the relationship between the projectile kinetic energy and the crater volume is about 1.5, which is rather smaller than 2.4 theoretically proposed by the scaling law in the strength regime. | |||||
