Comparative Analysis on the Interface Defeat Between the Cylindrical and Conical-nosed Long Rods

Based on the Alekseevski-Tate model, the present manuscript theoretically analyzes the interface defeat of cylindrical and conical-nosed long rods in their penetration process and the corresponding formulae of velocity decay and mass erosion of projectile are deduced out. In particular, with regarding the truth of quasi-static tail velocity of long rod in the interface defeat, the simplified and explicit analytical expressions of the dominated parameters with time, e.g. the tail velocity, eroded length and residual mass of the rod, are all formulated. Finally the kinetic energy loss of long rod is analyzed, and the effects of velocity decay and rod erosion on the kinetic energy loss of long rod are discussed. Especially, regarding the conical-nosed long rod, the effect of half apex angle on the kinetic energy loss is also analyzed.
