000015493 520__ $$2eng$$aNon-Crimp Fabric composites (NCFs) are characterized by their high specific mechanical properties and enhanced delamination resistance. To extend their use in car and airplane applications, predictive damage models are necessary. Damage phenomena initiation, however, may be strongly influenced by stress concentrations, which requires a realistic geometrical modelling to capture accurately stress states at damage initiation sites. Yet, current models remain geometrically simplified, and/or would require the actual manufacturing of the NCF specimen each time another NCF configuration needs to be investigated. Using principles developed in [1] and extended with NCF features, a RVE generator was developed that allows producing realistic geometrical models in a computational efficient and automated way. This discusses the RVE generation principles, illustrating that arbitrary shapes of NCFs can be obtained for different stitching parameters. Next, the geometrical models are discretized and used to investigate the influence of different stitching parameters on stress concentrations.
