爆炸成形弹丸(EFP)的研究表明,最终的形状与材料的种类及其延展性有直接关系.由经验可知,锻造一个尾部带有小凹窝的破片(EFP—编者)是可能的.但是在没有轴向断裂的情况下拉长EFP是困难的.同时在塑性变形中有能量损失,这就是我们研究空心弹丸终点弹道采用欧拉(eulerian)计算方法的原因.我们以1500—3000m/s速度发射,应用HULL编码计算破片的剩余质量、速度和侵彻。此外我们比较了铜实心和空心弹丸的实验性能,比较了铁和钽弹丸穿过轧制均质装甲(RHA)板后的实验性能。
Exploded projectiles (EFP) studies have shown that the final shape is directly related to the type of material and its ductility. From experience, it is possible to forge a fragment (EFP-Editor) with a small dimple at the tail. However, it is difficult to elongate EFP without axial fracture. At the same time, there is energy loss in the plastic deformation, which is why we study the eulerian method of trajectory trajectory of hollow projectile. We fired at 1500-3000m / s and applied the HULL code to calculate the remaining mass, speed, and penetration of the fragment. In addition, we compare the experimental performance of copper solid and hollow projectiles, and compare the experimental performance of iron and tantalum projectiles passing through rolled uniform armor (RHA).
