内容記述 | Rear surface velocities of the shocked natural snow plate were measured to study the distribution of particle velocities near the impact point. Impact experiments (v(sub i) = 100-700 m/s) were carried out by the collision between a spherical ice projectile (1.5 g) and a snow plate (porosity 64 percent) at variable plate thickness (0.3-4 cm). Rear surface velocities of the plate ejected from the impact point were measured by using an image-converter camera. Rear surface velocities of the plate decreased with increasing distance from the impact point and angle from the impact direction. Two-dimensional distribution of particle velocities in the plate was reconstructed using free surface approximation. In comparison with the previous works on the snow (porosity 30 percent), pressure attenuation derived from the particle velocity distribution varied from spherical one to elliptical one with a long axis along the impact direction with decreasing v(sub i) or increasing porosity. | |||||
