Abstract :
    The penetration into targets composed of concrete layer and semi-infinite foundation soil with flat-nose projectile is simulated with three-dimensional LS-Dyna finite element software. The deformation process and failure zone in the target are described. The penetration performance of projectile with flat nose is discussed. The penetration depth, the residual velocity and the deceleration amplitude of projectile increase with the initial velocity of projectile. And the penetrating cracks and the tensile crush zone indicate the damage of the target. The phenomena of concrete damage are in agreement with the experimental results.
