Unidirectional laminated textiles (UDLTs) are flexible non-crimped fabric structures, the UD layers ofwhich are bonded together by small amounts of thermoplastic resin and covered by polyethylene filmsover their external surfaces. Applications of them in ballistic protection clothes ensure lesser costs andability to resist the penetration of humidity, which may substantially decrease the overall ballisticstrength of the structure. This research focuses on the hierarchical multi-scale approach formulated forlarge displacement, material non-linearity and failure. The micro-scale model of UDLT represents matrixand fibres by means of 3D solid elements. A representative small volume (micro-cube) of the UDLT compositeis subjected to a series of large deformation tests up to the failure, which enable to approximatelyevaluate linear elastic and failure parameters of the orthotropic shell elements that represent themechanical behaviour of UDLT at rougher scale. Obtained longitudinal, transversal and shear strengthparameters in association with the corresponding strains are the parameters used at mezzo-scale in orderto calculate the Hashin criteria for the shell element failure. The results of the research are employed inorder to achieve reasonable computational costs during the simulation of ballistic penetration throughmulti-layer UD composite textile structures at medium velocity range.
