In order to study the anti-penetration performance of concrete, and obtain high penetration resistance concrete, mesoscale finite element model of different aggregate space distribution of concrete was established, the numerical simulation of long rod rigid projectile penetrating into different concrete was conducted. The results showed that aggregate settlement had great influence on target scabbing; aggregate size and settlement had limited influence on projectile residual velocity.
