| Abstract | ||
| Abstract In this work two models were created to verify the possibility of using Autodyn SPH 3D instead of costly pit tests. First model represents fragmenting of OG-7 warhead surrounded by 25 mm of sand to simulate partially a pit test for fragments recovery. The second model represents fragmenting of free OG-7 which was created to find out the effect of sand in fragments formation. The simulation results were compared with an experimental cubic pit test results. The experimental and simulation results were analyzed by Held’s formula for fragments mass distribution. | ||
