摘要

我们讨论了许多作者在对穿透金属薄板的钝硬弹丸进行数据分析时普遍存在的误解。他们分析的问题在于，他们使用了 Lambert 和 Jonas（1976 年）的经验关系，该关系是针对侵蚀射弹穿透厚板而提出的。相反，他们应该使用 Recht 和 Ipson（1963 年）基于物理学的模型来解释他们的数据。Wu 等人（2023 年）的论文就是这些著作中的一篇，我们利用他们的弹道学结果来证明 R-I 模型在解释他们的数据方面的优势。

A comment on “Plasticity, ductile fracture and ballistic impact behavior of Ti-6Al-4V Alloy” by Wu et al. (2023), Int. J. Impact Eng. 174:104493

We discuss a common misunderstanding made by many authors, regarding their data analysis for blunt rigid projectiles perforating thin metallic plates. The problem with their analysis is that they use the empirical relation of Lambert and Jonas (1976), which was suggested for eroding projectiles penetrating thick plates. Instead, they should use the physics-based model of Recht and Ipson (1963) to account for their data. The paper of Wu et al. (2023) is one of these works, and we use their ballistics results to demonstrate the benefits of the R-I model to account for their data.

期刊介绍： The International Journal of Impact Engineering, established in 1983 publishes original research findings related to the response of structures, components and materials subjected to impact, blast and high-rate loading. Areas relevant to the journal encompass the following general topics and those associated with them: -Behaviour and failure of structures and materials under impact and blast loading -Systems for protection and absorption of impact and blast loading -Terminal ballistics -Dynamic behaviour and failure of materials including plasticity and fracture -Stress waves -Structural crashworthiness -High-rate mechanical and forming processes -Impact, blast and high-rate loading/measurement techniques and their applications
