Effect of nose geometry on penetration capability of non-axisymmetric thin projectiles

چکیده
Hitherto, studies on impact by non-axisymmetric projectiles with high cross-sectional aspect ratios are limited, yet such cases may occur in a wide range of civil and military applications. A target response to geometry differs from that the extensively studied case axisymmetric projectiles. The focus this study is examine penetration capabilities plate-like various sharpness upon thin metallic targets. To end, attention drawn projectile’s geometrical parameters their effect characteristics. An experimentally-validated model was developed within finite-element-method (FEA) framework projectile-induced fracture velocity profiles, intention better understand occurring dissipation mechanisms identify contribution key parameters. change expected target’s reported, while linear section drop associated through relationship half-cone angle projectile. showed decreased resistance non-axisymmetric, high-aspect-ratio as compared equivalents.
