摘要

This research investigates the ballistic impact performance of multilayered armor augmented with sharp ceramic inserts against 9 mm caliber threats. The study explores the effectiveness of incorporating pyramid, cone, and blade-shaped ceramic inserts, utilizing materials such as alumina, boron carbide, and fiber cement, onto the armor's faceplate. The simulation model is initially validated against existing literature and subsequently modified to align with the proposed research objectives. The performance of the armor system is evaluated by comparing the directional deformation of the backing steel plate and the mass reduction of the armor resulting from the reduction in the faceplate thickness. The analysis focuses on assessing how the incorporation of sharp ceramic inserts influences the armor's ability to withstand BR2 9 mm Parabellum projectiles. Numerical simulations are conducted using ANSYS Explicit Dynamics with the Autodyne solver. The findings provide valuable insights into optimizing multilayered armor's design and material composition for enhanced protection against small caliber (BR2-level) threats.
