为了评估混凝土材料的抗冲击侵彻性能，基于既有的试验结果在4个冲击速度区间内围绕混凝土靶的破坏特点及若干要素对靶体行为的影响规律展开论述．总结2种主要的速度分区思路，建议综合考虑材料动力学响应特征和表观侵彻现象的4个速度区间，按照从低速到超高速的顺序展开论述：在低速区间内（撞击速度不超过40 m／s ）简要介绍梁、柱、板壳的破坏模式，中速区间内（撞击速度为40～1000 m／s ）论述弹靶相对尺寸、粗骨料、单轴抗压强度和钢筋对混凝土厚靶侵彻效应的影响，高速区间内（撞击速度为1．0～2．0km／s）描述半流体转变速度和成坑效应，超高速区间内（撞击速度超过2 km／s）描述密度效应占主导的流体侵彻行为．对未来混凝土材料侵彻效应的研究提出若干建议．

Impact experimental results for concrete targets and the factors influencing target behaviors in four velocity ranges were presented in order to evaluate the impact resistance of concrete .Two types of velocity partition means were concluded and four velocity ranges were suggested based on material dynamic responses and apparent penetration behaviors .The experimental studies were reviewed from low velocity to hypervelocity .In low velocity range(impact velocity within 40 m/s) ,failure modes of beams ,columns , slabs and shells were briefly summarized .In medium velocity range(impact velocity between 40 m/s and 1 km/s) ,the effects of relative diameter of missile to target , coarse aggregate , uniaxial compressive strength and steel bar on the thick target penetration were discussed . In high velocity range (impact velocity between 1 km/s and 2 km/s) ,the semi‐hydrodynamic transition velocity and cratering effects were introduced .In hypervelocity range (impact velocity over 2 km/s) ,the density‐dominant hydrodynamic penetration phenomena were described .Some research proposals on concrete penetration were given for the further study .
