Effects of Different Projectile Nose Shapes on the Impact Performance of the Aluminium 2024 Thin Plate
In this study, the impact performance of the Al2024 thin plate target was determined through a numerical approach. Two different-nosed hard steel projectiles, including a blunt and a sphere, were used in order to obtain the ballistic impact of the target. ANSYS Autodyn was used to model a threedimen...

| description | In this study, the impact performance of the Al2024 thin plate target was determined through a
numerical approach. Two different-nosed hard steel projectiles, including a blunt and a sphere, were used
in order to obtain the ballistic impact of the target. ANSYS Autodyn was used to model a threedimensional (3D) model that corresponds to a previous experimental study. The ballistic resistance of the
target was numerically evaluated in terms of ballistic limit velocity, residual velocity, and energy
absorption and compared at different incident angles such as 0°, 15°, and 30°. To validate the numerical
outcomes, the Recht-Ipson model was used as a reference benchmark. The results of this investigation
showed that when the incidence angle of a sphere-nosed projectile increased, the target's ballistic
performance decreased. In contrast, the target’s ballistic resistance against a blunt-nosed projectile was
little affected by the impact angle. According to the findings, the simulation results are consistent with the
published numerical and experimental outcomes. |
