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 FE 2 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)
