【Abstract】

<正>This study presents the influence of the nose shape of projectile on the local damage of concrete plates subjected to high-velocity impact.First,the projectile launching apparatus by high-pressurized air was developed.This apparatus can launch projectiles with the mass of 100g to 1000g.Then,impact tests for concrete plates were carried out.After that,a numerical model which can describe the local damage of concrete plates was investigated by using general purpose hydrocode AUTODYN in terms of a constitutive model and strain rate effect.Finally,the influence of the nose shape of projectile on the local damage of concrete plates was discussed by numerical simulation.
