Abstract (EN): An Offset-reduced Unit Cell (OrUC) model of a 5-harness satin weave is used to characterise damage evolution in this textile composite. Non-linear material models for both yarns and epoxy resin embedding the yarns are applied to the numerical analysis. The epoxy resin is represented by an elasto-plastic with damage constitutive model while the yarns are modelled making use of a transversely isotropic damage model recently proposed. Different loading conditions are applied to the OrUC, allowing for a detailed study of damage initiation and evolution inside the satin weave up until complete failure.
