混凝土靶高速侵彻的模型律

SIMULATION ANALYSIS OF HIGH VELOCITY PENETRATION INTO CONCRETE TARGET

采用量纲分析的方法 ,总结近年来国内外有关混凝土类靶材贯穿实验的大量数据 ,对混凝土类材料靶高速贯穿的规律进行了研究 ,发现混凝土类材料靶和金属靶一样 ,也基本上遵守穿甲过程的相似律 ,并以一种新的观点解释了应变率效应对穿甲过程模型律的影响 ,最后通过对实验数据的拟合 。

Many ballistic tests data of high velocity penetration into concrete target are analysed in the paper. Though concrete material target an obvious strain-rate effect the penetration results have shown a good accordance with simulation rules much the same as that of metal material target. A new opinion is suggested to explained the influence of strain-rate on simulation rule. Using fitting program a dimensionless penetration equation is obtained in the end.
