The main purpose of this paper is to optimize the format of a projectile top in collision and vertical penetration considering the velocity drop and the projection as a contend purpose function. In order to fulfill this purpose. at first. Modeling of limited puts is done using ABAQUS / Explicit software and by the various geometrical dimensions. The penetration of projectile is being tested and consequently a data table produced.

At the next stage this data is utilized to train and test the Neural Net Work of GMDH type to reach a mathematical model for expressing the velocity drop. In...
