Material Models for Fabric
Material models for fabric
The image shows a dialog box for defining the material type "Fabric" for surface elements. Below it, the selection list of material models is open, containing two options: "Orthotropic | Linear elastic (Surfaces)" and "Orthotropic | Fabric | Nonlinear elastic (Surfaces)". These material models allow for a realistic representation of the orthotropic behavior of fabric membranes, in which the stiffnesses in warp and weft directions differ. In addition, nonlinear elastic models take into account the load-dependent stiffness development of the fabric, which is essential for the accurate analysis of membrane structures.
