In order to simulate 3D interlock composite reinforcement behavior during forming process, it is necessary to predict yarns positions in the fabric during the preforming stage of the process. The present work deals with thick 3D interlock fabric forming simulation using specific hexahedral semi-discrete finite elements. Using the virtual work principle, we distinguish the virtual internal work due to tensions in yarns from other internal virtual works. The stiffness relative to yarns tension which is the main part of the rigidity is described by bars within the elements. The other rigidities - like transverse compression, shears or friction between yarns - are depicted by a continuous additional material. A combination of this "first order"...
