The ballistic responses of the composite targets composed of the corrugated ceramic block and corrugated steel plate were investigated by numerical simulation. The effects of the composite target configuration on the projectile residual velocity, the failure mode, and the energy absorption of targets were analyzed.The ballistic performance of the composite target with composites back plate was discussed. The results show that the projectile impacting on the slope of the target has the least residual velocity of projectiles, and the slope of the target can remarkably change the trajectory of the projectile. Adding the corrugated UHMWPE composites plate along the direction of the steel back plate of the configuration can effectively improve the overall anti-penetration performance of the configuration.

“…The backing plate is utilized to hold the cracked ceramic in place and absorb the projectile's remaining energy, while the ceramic coating serves to blunt and reduce the velocity of the projectile [6][7]. According to Zhao et al [7], experimental and simulation studies were used to create armour utilizing three different methods: bi-layer armor, mosaic armor, and honeycomb armor. The projectile was made out of Steel 4340 and was fired at speeds ranging from 242 m/s to 725 m/s.…”

This research aims to determine the effect of the panel configuration which has the strongest resistance and to analyze the ballistic toughness of the Al2O3 and Weldox 460 E Steel panel configurations. The criteria to be looked for are the Depth of Penetration, Deflection and Final Projectile Length. To determine the accuracy of this study, a verification of the simulation research previously conducted by Dey et al. The method used is based on simulation with the finite element method. The software used is ANSYS/Explicit Dynamic solver AUTODYN 18.1. The modeling used in this study is simplified into 2D Axisymmetric. Alumina and Weldox 460 E steel panel configuration variations that will be used in this study. There are 7 variations of the panel configuration used, namely B12, A5B5, A5B10, A10B5, A10B10, A12B12 and A15B15. Alumina material as the front panel, while Weldox 460 E as the back panel. In calculating the mechanical behavior of the material, while the Alumina material uses the Johnson Holmquist (JH2) Strength parameter. And then, the Weldox 460 E material uses Johnson and Cook parameters. The results obtained indicate that the A12B12 and A15B15 panel configurations are able to withstand projectiles. The A12B12 panel configuration has a depth of penetration value of 23 mm, a deflection value of 4.3 mm and a Vbl value of 954.69 m/s. while the best panel configuration is A15B15 with a depth of penetration value of 21 mm, a deflection value of 1.4 mm and a Vbl value of 1345.9 m/s. then the conclusion of this study shows that the A15B15 panel configuration is the best panel configuration that is able to withstand projectiles.

“…Existing studies of multiple ballistic impacts targeted mainly fiber-reinforced composites 13−17 and ceramic/metal armors. 18−21 For instance, multiple ballistic impacts of fragment simulating projectile on S-2 glass/SC15 laminates were investigated, both numerically 13 and experimentally. 14 The initial impact damage was found to extend towards the supporting edges of the laminate, resulting in about 4.5% and 9% decrease in multi-hit ballistic limit velocity and energy absorption, respectively.…”

“…20 The present authors used a combined experimental and numerical approach to investigate the ballistic behaviors of ceramic/metal bi-layer mosaic armors as well as metallic honeycomb enhanced mosaic armors. 21 Special focus was placed upon quantifying the influence of ceramic tile size, impact position, border-effect, and inter tile gap width on single and multiple ballistic impact resistance. It was demonstrated that relative to monolithic ceramic armor and traditional bi-layer mosaic armor, the honeycomb-enhanced mosaic armor could efficiently localize the extent of damage after the first strike and maintain effective bonding between adjacent ceramic tiles and the back metallic plate, thus enabling balanced single and multiple impact resistance.…”

The ballistic performance of protective structures under multiple projectile impacts attracts increasing attention due to its practical importance, and existing studies were seldomly devoted to exploring how the structure would deform and fail when subjected to such loads. This study aimed to characterize the multi-hit ballistic resistance of fully-clamped thin plates made of 304 stainless steel using finite element method, with the equivalent plastic strain employed to define material damage and failure/fracture. The numerical model was validated against existing experimental results of double impacts at the same location, with good agreement achieved. The model was subsequently employed to quantify the effects of impact position, interval time between successive hits, projectile nose shape (e.g., spherical, flat and conical), and boundary condition of target plate on ballistic limit and deformation/failure modes. Further, ballistic limit boundaries were constructed for both double and triple impacts of projectiles. Obtained results are helpful for designing high-performance protective structures against multiple projectile impacts.
