摘要：
This study is to investigate the mechanism of local damage in a concrete plate by the impact of hard projectile with a hemisphere-nose. Thus, to execute the experimental study, testing apparatus for launching the projectile was newly developed. Using this apparatus, a projectile with the mass of 100g is shot by at a velocity of about 500m/s. In this test, the relation between the impact velocity and the penetration depth and crater diameter were examined. The impacting appearance was recorded by a high-speed video camera, and then analyzed. Also, to find the mechanism of local damage in concrete, a numerical simulation by AUTODYN was performed.
