长杆弹高速斜穿甲工程计算公式
An Engineering Formula on the Calculation of Oblique Penetration by Long-Rod Projectile
-
摘要: 本文提出了一个实用的高速斜穿甲公式.它是根据本文提出的高速碰撞时应以应力冲量.而不是以应力本身作为破坏参数而导出的.所得公式与大量已有试验数据相符得很好.Abstract: Based on the concept supposed in this paper that damage of a target is determined by momentum rather than by stress,an engineering formula on the calculation of oblique penetration by long-rod projectile is established.The results calculated from this formula show good agreements with experimental data.
