Abstract

Abstract: This article examines the characteristics of a penetrator with a triangular cross-section perpendicular impacting a semi-infinite metal target. Experiments and numerical simulations were conducted at an impact velocity of 1600 to 1800 m/s. The model, which was constructed to analyze penetration depth, showed the effect of the nose-shaped structure of the penetrator on penetration characteristics. The model can analyze the penetration characteristics of a penetrator with triangular cross-section that attacks semi-infinite targets. The results obtained by the model are primarily attributed to the self-sharpening characteristics of the penetrator.
