Analysis and Comparison of Projectile Penetration Models into Semi-Infinite Metal Targets

In this paper four different models which have been presented to analyze the penetration of projectile into semi-infinite targets are compared and contrasted Tate and Alekseevskiiʹs models are considered as the basic refrence models. Vahediʹs model is particulary well suited in design situations. Luk ʹs model uses conservation laws and considers the effect of mushrooming while penetrating into target and Walkerʹs model considers the transient phenomena in penetration process. The results related to these models are compared with experimental data and some recommendations are presented.
