| Abstract Scope |
Polyurea, a versatile block copolymer, is widely applied in impact-resistant applications like protective gear and structural reinforcements. Its unique molecular architecture, featuring hard segments for rigidity and soft segments for flexibility, provides remarkable elasticity and toughness. Additionally, polyurea dissipates stress from high-velocity impacts through the breaking of hydrogen bonds. This study employs molecular dynamics simulations in LAMMPS to investigate polyurea's nanoscale response to high-velocity impacts. We analyze temperature fluctuations, stress propagation, and failure mechanisms to better understand its performance under extreme conditions. These insights are valuable for designing enhanced materials for impact-resistant applications, such as body armor. By simulating scenarios difficult to replicate experimentally, this work highlights the utility of computational methods in advancing material design for high-performance and safety-critical applications.
