Assessment of ballistic impact damage on aluminum and magnesium alloys against high velocity bullets by dynamic FE simulations

Abstract The shape of the projectile seems to determine effect a ballistic impact and failure mechanism. In this study, numerical analysis with different shapes, i.e ., ogive, blunt, conical, hemispherical is performed. target circular sandwich plate an outer diameter 315 mm, which composed three layers thickness 1 mm for each layer. These will be filled materials such as 1100-H12 aluminum alloy, ZK61m magnesium 6061-T651 alloy. in consists two parts: inner zones. zone, selected element size set fine, while it coarser, increase along direction circle. This simulation uses Johnson–Cook material model applied ABAQUS/Explicit software. configurations are validated based on previous experiments by comparing residual velocity values after has penetrated plate. results obtain energy absorption variation affected stress strain radial, circumferential, axial, shear deformation. value determines strength Then compare arrangement strongest when receiving loads.
