Numerical Simulation on Impact Performance of Ceramic-Based Ultra-High Molecular Weight Polyethylene Composite Armor
Abstract
This paper aims to investigate the anti-penetration capabilities of ceramic composite armor backed by a layered composite of Titanium Alloy Grade 5 (Ti6Al4V) and ultra-high molecular weight polyethylene (UHMWPE) against a high-velocity 12.7 mm diameter projectile traveling at 818 m/s. The study employs numerical simulations using Ansys software to analyze the bullet-proof mechanism of the entire armor system, as well as the performance of the UHMWPE layer in isolation. By focusing on the behavior of these armor layers during impact, the study provides insights into how different materials contribute to energy absorption and resistance to penetration. A key aspect of this work is the comparison between simulations using both rigid and flexible projectiles, allowing for a more comprehensive understanding of the impact dynamics. This research contributes to the broader field of armor design and impact resistance by offering a detailed analysis of the interactions between projectiles and multi-layered composite armor systems. The findings have potential applications in the development of more efficient and reliable ballistic protection systems, where material optimization and structural configuration are critical factors in enhancing performance against high-velocity threats.
