Used the LS-DYNA procedure to set up numerical model on penetration of semi-infinite aluminum-alloy targets by tungsten-alloy rod over a wide velocity range has been discussed. The mass of penetrator is about 46.7 g with a length over diameter ratio of 15. Based on experiment results from the reference, distinguished analytical models were used individually in case of relative high impact velocity and low one, and parameters of constitutive equations including failure parameters for aluminum alloy 7020 and tungsten alloy were calibrated. Penetration experiments within the impact velocity from 200 m/s to 2 500 m/s were numerically simulated, and the numerical results were in good agreement with experiments. In addition, the effect of projectile nose to penetration was investigated, and the relationship between length over diameter ratio and penetration was obtained. In the case of high impact velocity, the nose shape has little effect on penetration. Numerical results indicate that dimensionless penetration decreases as length over diameter ratio increases.
