A Numerical Model For Ballistic Impact Response of Composite Armors

Abstract

In this study, we present a numerical model to simulate the ballistic impact of a rigid right circular cylinder(RCC) projectile into a woven fabric target. The numerical solution of transverse ballistic impact on a laminarbiaxial fabric is obtained using a forward finite-difference method. The ballistic impact analysis for differentmaterials of targets made of aramid and polyethylene fibers are simulated to investigate the effect of fabricmaterial on the ballistic resistance. Numerical simulations are performed to reveal the influences of crimp factorand fabric material on the ballistic performance of woven fabrics. Various cases have been presented showingthe variations of yarn strains, yarn velocities, and yarn displacements over time.
