Abstrakt: The increasing use of finite element simulation in the field of composite material forming involved in the past few years a large amount of research on the constitutive modelling of textile material at the mesoscopic scale (i.e. the scale of individual fiber tow). Up to now, the community interest was focused on a consistent shape prediction. Moreover, the large amount of contacts between yarns imposed the use of dynamic explicit approaches for numerical efficiency reasons. Recent advances in contact algorithms make now possible the use of implicit schemes. The present paper shows how a constitutive equation written and implemented in the dynamic explicit scheme with ABAQUS/Explicit is adapted to implicit one (i.e. ABAQUS/Standard), for large displacement analyses.Validation and perspectives are illustrated on a weaving operation.
