résumé Textile fabric is a very useful material for protection against ballistic projectiles. A numerical analysis performed using the finite element method, has been carried out to understand better physical and mechanical phenomena during a ballistic impact on 2D Kevlar KM2® plain-woven fabric. The study is two folds: macroscopic and mesoscopic with shell elements in explicit scheme of the finite element method. The numerical problems, dealing with the influence of the number of shell elements in a cross section for having correct models are analyzed. The damage mechanisms of the fabric during penetration time of the projectile are discussed and compared to literature experimental results. The agreement with experience results onto damage mechanisms and residual velocities shows a good validation of this study.
