An efficient finite element model of the ballistic impact and perforation of the woven fabrics structures has been developed in LSDYNA. The bullet has been considered as a deformable body in contact with the fabric package presented by interwoven yarn structure. The simplification of the model has been achieved by presenting the multifilament yarns by thin shell elements the thickness of which represents the real thickness of yarns as it can be measured in the weave. The zones of the fabric remote from the point of impact have been presented as a roughly meshed uniform membrane model. The junction between the two types of zones of the fabric has been performed by means of the tie constraint and by proper adjustment of material parameters ensuring the minimum cumulative wave propagation speed error along selected directions. The model has been verified by comparing the response of the structure with the reference solution obtained by solving the full woven structure model. Physical and numerical experiments have been performed in order to identify the material model parameters.
