title = "A finite element model for plain weave fabrics based on an inner beam structure",
abstract = "The paper presents a finite shell element for plain weave fabrics. It is designed for draping and forming simulations. Instead of a classical constitutive law, a unit cell is modeled with crossed beams. With that approach, it is possible to describe the kinematics of the fibers in a natural way. The structure of the unit cell is presented. The setup of the system of equations for the unit cell and the formulation of the boundary conditions is explained. The nonlinear problem is solved with a Newton iteration. Shearing is not considered in the unit cell. Hence shearing effects are taken into account via a so-called parent sheet. Based on these assumptions, the membrane behavior of the element is described. Bending behavior is calculated with the Mindlin plate theory. Due to the separate treatment of in plane and out of plane behavior, the bending characteristic is decoupled from tension/compression. The unit cell model is implemented in the user material environment of the industrial explicit FE program PAM-Crash. The presented work is related to draping, but the method offers new opportunities for any application where the inner structure of a material plays an important role.",
