| Abstract: | In this paper a modification is made to the theory of perforation given by Dikshit and Sundararajan (Int. J. Impact Engng. 12(3) (1992) 373–408). In their analyses an empirical equation is used to compute the normalized size of the plastic zone around the projectile path in the target material. In this paper by assuming that the heat generated in the perforation process effects only in the plastic zone, an analytical equation is introduced instead of an empirical relationship for computation of the normalized size of the plastic zone. The final results of this paper are in good agreement with those of Dikshit and Sundararajan. |
