In the textile composite drape process, the material bending behavior plays a critical role in the onset and development of wrinkles. The bending moment is linked with the membrane forces in the classical shell element which leads to the insufficient

Understanding the mechanical properties of carbon fiber reinforcements is necessary for the simulation of forming processes. A unit-cell mesoscopic model provides a tool to implement virtual material characterizations which can be served as an input
