Modelling of cyclic visco-elasto-plastic behaviour of coated woven fabrics under biaxial loading and finite strain

International audienceThis paper deals with the modelling of the mechanical behaviour of coated woven fabric. The proposed model takes into account the individual behaviours of the yarns, the coating and their interactions including the influence of the angle variation between warp and weft yarns. This model is able to describe simultaneously the non-Newtonian viscous behaviour, the time-independent irreversibility, the anisotropy and the cyclic loading behaviour. The model was implemented in the finite element code ABAQUS and enables calculations on structures such as complete sails
