This contribution deals with rope-like textiles. On the macroscopic level rope-like textiles are characterized by a large length-to-thickness ratio, such that a discretization with beam elements is numerically efficient. To capture the contact behavior the representative volume element is explicitly modeled by means of a volumetric micro sample. A suitable, beam-specific FE2 method is developed, which connects the homogeneous macro level to a fiber structured micro sample. This contribution investigates the determination of the nonlinear constitutive behavior of rope-like textiles. Selected examples for the macroscopic behavior of microscopic heterogeneous fiber structured materials are presented. (© 2014 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim)
