混凝土靶高速侵彻的模型律

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,给出混凝土类材料靶贯穿过程无量纲最大穿甲深度的无量纲速度的表示式。

SIMULATION ANALYSIS OF HIGH VELOCITY PENETRATION INTO CONCRETE TARGET

Many ballistic tests data of high velocity penetration into concrete target are analysed in the parper. Though concrete material target has 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.
