2.1.8 Fabrics

The modeling of very thin structures and fabrics is characterized by the fact that tension can be transferred but compression cannot be transferred because the structure immediately starts to wrinkle. This behavior can be modeled with a special wrinkling element [Vol. Element Library]. These elements can only be used with linear elastic material properties. Geometric nonlinear effects due to large displacements have to be taken into account by the GEOMET analysis command option [Vol. Analysis Procedures].
