Abstract
In order to destroy the hard target, it is essential to develop a penetration warhead with high penetration performance. To design a penetration warhead, this paper discusses the effect of nose shape factors such that nose shape, nose length, nose tip diameter, on the penetration performance of the penetrator. AUTODYN-2D has been used to conduct the computational analysis. The experimental result of Forrestal, and a simulation result have been compared to verify the reliability of computational analysis. Computational results show that the nose length have more influence on the penetration performance than the nose shape. Furthermore, simulation results show that the penetration performance can be improved by increasing the nose tip diameter to a specific value, when the nose length of the penetrator is uniform.
