This study presents a finite element analysis of the ballistic impact behavior of hard bulletproof vests, focusing on the influence of multilayer armor design. Using Abaqus/Explicit, a ceramic/composite armor system is modeled and subjected to various projectile velocities, layer thicknesses, and projectile diameters. The research evaluates target damage modes, residual projectile velocities, and energy absorption mechanisms, providing insights into the optimization of armor configurations for improved ballistic resistance while minimizing weight.
