Abstract：Based on the penetration experiments, the penetration mechanism of steel tube confined concrete targets against 12.7mm armor piercing projectile(APP) was simulated with LY-DYNA software, finite element-smooth particle hydrodynamics method and CSCM_CONCRETE model. The results show that: the simulation agrees well with the experiments, which can well describe the hoop cracks on side face of the steel tube confined concrete; the confinement effect of steel tube on the confined concrete works while the projectile expanding; the mechanism of the hoop cracks on side face of confined concrete is the mutual results of the incident compression wave, reflected stretching wave from distal face and the confinement of the steel tube; the ability of steel tube confined concrete target is higher than that of normal concrete target.
