eme ng a ics a mo ul is t tive of this constitutive model is defined by the fibre rotation. This constitutive model is implemented in ABAQUS and can be used in most commercial F.E. software. The approach is extended to materials with ortanc posite ng, the rface i esin tr direction and density of the fibres after forming. These directions and densities can be significantly modified by the forming process in the case of a shaping on a double-curvature surface. This infor-mation is very important for structural analyses of the composite part in use (stiffness, damage, fatigue,...). Some approaches have been developed for woven fabric drap-ing simulations based on ‘kinematic models ’ [4–6]. In these meth-the yarns) and at the micro-scale (scale of the fibres) influence the macroscopic behaviour of the fabric. Despite multiple efforts in this field, there is no widely accepted model that describes accu-rately all of the important aspects of fabric mechanical behaviour. The main model kinds come from the multi-scale nature of textile. Some approaches have been recently proposed in which the com-ponents at meso-scale (yarns) or micro-scale (fibres) are modelled [7–11]. Nevertheless, because of the very large number of yarns or fibres in a composite part and their complex interactions, these ap-proaches are (today) limited to small-domain analyses. If these ap-proaches are used for complex part forming simulations, th
