Dynamics Algorithm for the Projectile Shell Movement Course Generated by Ammunition Group Blast

结合爆轰物理学和材料学的有关理论,对弹药群爆时弹丸壳体的塑性膨胀变形过程进行了分析,建立了弹药群爆条件下的弹丸壳体运动速度的动力学算法,计算出了弹丸壳体膨胀破裂时的半径和形成破片的初速。

According to the theory of detonation physics and material science,the plastic deformation expanding process of projectile shell generated by ammunition group blast was analyzed,the movement speed dynamics algorithm of projectile shell was established,and the breakage radius and the velocity of fragments generated by ammunition group blast were calculated by the established dynamics algorithm.
