| Abstract: | The smoothed particle hydrodynamics equations that include the entire stress tensor are formulated. The SPH method program is used in simulating the problems of high velocity impact. Two calculating models, which include normal impact and sloping impact, are simulated, and the results are rational. It is demonstrated that SPH method can be applied to solving impact problems. |

| Keywords: | smoothed particle hydrodynamics high velocity impact numerical simulation |
