A study on perforation prediction of metal targets by cylindrical tungsten penetrator

In present study, simulation results of tungsten penetrator are compared with the experimental results in order to confirm the predictions for residual velocity. The cylindrical tungsten penetrator with conical tip and flat tip were used for the experiment and simulation. The metal target material were made of SM 20C, titanium and aluminum. The dimension of the target was 100 × 100 × 5 (mm 3 ). The range of initial velocity was from 400 to 1500 m/s. AUTODYN-3D simulation was used to study the perforation effect of penetrator. The simulation results were confirmed with experimental results within 10%. The assessment accuracy was achieved by applying the erosion value.
