摘要
通过测量 35CrMnSi弹钢的静态拉伸性能 ,获得了材料从 2 .5mm到 2 8mm不同直径试样的屈服强度 ,然后采用动力有限元计算的方法计算了直径比在 10∶1以上弹丸侵彻钢装甲时的侵彻性能。结果发现 ,有尺寸效应后 。
Through measuring the static tension performance of 35CrMnSi projectile steel, the yield strengthes of samples with diameters from 2.5mm to 28mm have been obtained. And the penetrating capacity of the projectiles with length-diameter ratio of over 10 was also calculated by dynamic finite element method. The results show that when size effects occur, the interactions between projectiles and targets don't accord with geometrical similarity law.
