DYNAMIC RESPONSE OF PLAIN-WOVEN FABRIC SUBJECTED TO BALLISTIC IMPACT OF FLAT-NOSED PROJECTILE
An available code, LS-DYNA, was used to model the dynamic responses of plain-woven fabric under impact of a flat-nosed projectile. The fabric deformation, yarn breakage, impact load and time history of energy absorption mechanism were investigated, and effects on the fabric dynamic responses by different impact velocities of projectile were also discussed. The simulation results showed that the yarn strain and kinetic energy, and frictional sliding dissipated energy were the dominant energy transfer of kinetic energy of projectile. Simulation results also indicated that energy absorbed increases with impact velocity of flat-nosed projectile up to a critical impact velocity before it starts to decrease. The numerical simulation results were compared with existing experimental results, both transverse deflection in the yarns and energy absorption characteristics of fabric are consistent with the experimental results.
