Abstract

An analytical model of penetration analysis of ogival projectiles into metallic target has been presented by Dikshit & Sundararajan (1992). That model under condition of negligible deformation of projectile has given good results, but in the real case of current projectile with considerable deformation due to impact, it overestimates the depth of penetration. In this paper; the plastic work done on the projectile during the penetration process has been evaluated and as a considerable dissipating energy added to the other three dissipating energies involoved in the initial model of Dikshit & Sundararajan. Besides, a series of ballisic tests using 7.62 and 5. 56mm projectiles and steel plates have been done and the experimental results compared with analytical solutions.This Comparison shows that the modified model of this paper gives appropriate estimation for depth of penetration and may be used for further parametric studies and designing of metallic targets.
