摘要
以动能弹侵彻、穿透混凝土靶为例，较详细地说明了在数值模拟这类问题时，必须正确选择混凝土的本构关系，还必须特别着重考虑空穴的压实效应和损伤效应，否则数值模拟得到的结果在定量和定性上都将偏离实验较远。本文计算动能弹侵彻、穿透混凝土靶的二维程序为二维拉氏（FCM）程序和二维拉氏有限元程序（LTZ－2）。
In this paper, we conclude that before numerical simulation for the penetration of a kinetic bullet through the concrete target is to be made, it is necessary to select the constitutive relation of concrete correctly and put special emphasis on consideration of the demage and collapse of pores. Without that the results obtained from the numerical simulation may have a significant deviation from those obtained from experiments. When computing the penetration of a kinetic bullet through the concrete target, we use the 2D Lagrangian program LTZ-2 and FCM.
