| 摘 要： | 本文用分子动力学方法研究了高应变率下晶体材料的力学行为。在冲击加载下，晶体材料中产生了位错和塑性变形。在强冲击时还可出现相变变化。在讨论应变率变化时，获得了屈服强度随应变率增大而增高的结果。

| Abstract: | Molecular dynamics is used to investigate the mechanical behaviour of crystal material at high strain rates in this paper. Dislocation and plastic deformation was produced in crystal material under shock loading.phase change could occur when shock loading was strong. It was obtained that the yield strength was increased as the strain rates were raised. |

| Keywords: | strain rates plastic deformation molecular dynamics |
