Comparative Study of Nose Profile Role in Long-Rod Penetration

Abstract

In this paper the penetration depth of long-rod electromagnetic projectiles on semi-infinite targets are studied with numerical approach. And the role of nose profile was studied. The results obtained from this investigation were compared with the recent studies. For the targets and projectile were considered to be made of soft metals. All the results were compared with two analytical models: Tate and Vahedi. These two models don't consider the role of nose profile. The target is constrained to have no movement and the projectile doesn't pass through the target. The impact velocity of the projectile was considered as a variable and the results were compared together and they were in good agreement with other studies in this field.
