Abstract
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
