| Research Abstract |
When projectiles (aluminum alloy spheres) strike thick plates made of aluminum alloys at velocities over 1 km/s, ejecta and ejected behavior were examined and formation mechanics were clarified. In particular, when temperature of thick aluminum alloy plates and impact angle of projectiles were changed, ejecta angle and distribution of mass and size were examined. The scale laws and main factors affecting ejecta behavior were discussed.
