摘　　要：本文应用MEPH程序数值模拟了击靶速度小于3km/s的φ4mm的钨珠对铝靶、钢靶的侵彻,并对计算所得的结果进行了理论分析,与有关实验比较。对弹丸的形状、靶材厚度对穿深的影响也给出了一部分结果。This paper is concerned with the evolution of the aluminium or steel target which is penetrated by a wolfram ball, in which the ball's velocity is less than 3km/sec and its diameter 4mm. The significant results are obtained by means of the numerical modelling using MEPH code,and compared with the experiments also. The numerical and analytical studies indicate that the depth of penetration is in close relationship with the shape of pellets material and thickness of the target.
