Effective and reasonable computational models are established to simulate the penetrating processes for the tungsten fiber reinforced tungsten alloy matrix composite penetrators and the tungsten alloy penetrators by the DYNA 3D finite element program. The simulation results are compared and verified by the penetrating experiments. The reason that the penetrating performance of the tungsten fiber reinforced tungsten alloy matrix composite penetrator is superior to that of the tungsten alloy penetrator is discussed.These results can provide reliable theory,computational models and experiment bases for further research.
