摘要：
A finite element simulation of fibre fabric shaping process is proposed. The behaviour of fabrics is experimentally studied from biaxial tensile tests. on cross shaped specimens. These experiments permit to investigate the influence on the fabric behaviour of the undulation variations of the weaving and of the interactions between warp and weft yarns. A constitutive model including these aspects is proposed, validated and identified from the biaxial tests. Finite elements made of woven yarns are built in the field of non-linear kinematics. The deformation energy is calculated as the sum of the energy of each elementary cell for which the biaxial behaviour previously identified is considered. A drawing simulation with square punch and die is presented. It allows to distinguish the geometries of the tools which are possible or not for the shaping process. The influence of the undulation Variations are studied in a second example. (C) 1997 Elsevier Science Limited.
