| ABSTRACT Design of a warhead that forms upon detonation an explosively formed penetrator (EFP) capable of penetrating a specific rolled homogeneous armor (RHA) is the main theme of this paper. Six different preliminary warhead models have been simulated using Autodyn-2D code. The main features of each EFP formed from each preliminary model are predicted. The obtained results serve in determining the design parameters of the required (refind) warhead model. In addition, the simulated EFP from the refined warhead model and its penetration into a specific RHA have been simulated. Samples of the obtained predicted results by the code for EFPs formed from different preliminary and refined warhead models, respectively, are presented with relevant analysis and discussions. For the refined warhead model, the code predicts that the obtained EFP has a high velocity, high aspect ratio and is capable of penetrating the RHA to the specified thickness. Moreover, the influence of explosive type, its aspect ratio and liner material of the refined model on the formed EFP have been predicted. | ||
