After introducing the major algorithm and the development of numerical simulation

the dynamic finite element program LS-DYNA is used to simulate earth penetrating weapon penetrating concrete.A model is established and calculated by Lagrangian algorithm to get the penetrating figure

velocity curve and the acceleration curve.The results indicate that the velocity and the acceleration are reduced with penetrating process nearing stabilization while penetrating concrete at 35 μs.And it is consistent with literatures.The numerical simulating results can offer assistance for the design of earth penetrating weapons.
