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.

三角形截面侵彻弹侵彻半无限目标的侵彻特性
摘要
本文研究了具有三角形横截面的穿甲弹垂直撞击半无限金属目标的特性。实验和数值模拟是在 1600 到 1800 m/s 的冲击速度下进行的。为分析侵彻深度而构建的模型显示了侵彻器鼻形结构对侵彻特性的影响。该模型可以分析三角形截面穿甲弹攻击半无限目标的侵彻特性。该模型获得的结果主要归因于穿甲弹的自锐特性。
