Popis:	This paper presents a meso-level FE model of unidirectional yarns in order to point out the difference in impact response for two materials: glass and aramid fibers. The architecture is kept the same, successive layers of yarns, oriented 0° and 90°. The constitutive model for each yarn material is bilinear with hardening, as taken from recent documentation. The projectile is a 9 mm FMJ with the geometry close to the actual one and the metallic alloys for core and jacket are also bilinear with hardening. There were analysed the stages of the impact and failure process, the equivalent stress distributions on yarns and, based on the simulation results, the authors made recommendations for an actual design of a ballistic protection system.
