复合材料纺织增强体清晰的多尺度结构导致其成形模拟的连续和离散方法的发展。本文提出了基于亚弹性和超弹性本构模型的两种连续模型。还考虑了一种离散方法，其中每根纱线由壳有限元建模，并考虑了纱线之间的摩擦接触和可能的滑动。最后提出了半离散方法，其中壳有限元插值涉及位移场的连续性，但其中的内部虚功作为所有编织单元内的单元的张力、面内剪切和弯曲的总和而获得。不同的方法的优点和缺点进行了讨论。
The clear multi-scale structure of composite textile reinforcements leads to develop continuous and discrete approaches for their forming simulations. In this paper two continuous modelling respectively based on a hypoelastic and hyperelastic constitutive model are presented. A discrete approach is also considered in which each yarn is modelled by shell finite elements and where the contact with friction and possible sliding between the yarns are taken into account. Finally the semi-discrete approach is presented in which the shell finite element interpolation involves continuity of the displacement field but where the internal virtual work is obtained as the sum of tension, in-plane shear and bending ones of all the woven unit cells within the element. The advantages and drawbacks of the different approaches are discussed.
