This contribution deals with textile materials. On the macroscopic level textiles are characterized by a large area-to-thickness ratio, such that it is numerically efficient to treat the textile structure as a shell. To capture the contact behavior, fibers within a representative volume element are explicitly modeled by means of one dimensional beam elements on the microscopic level. A suitable, shell-specific homogenization method is developed, which connects the homogeneous shell specific macro level to a fiber structured micro level. This contribution investigates the determination of the nonlinear constitutive behavior of textile materials. Selected examples for the macroscopic behavior of microscopic heterogeneous fiber structured materials are presented. (© 2015 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim)

    In the current stage, left-handed material (LHM) has aroused wide interest based on several basic prototypes such as metamaterials. In this work, we have theoretically investigated the possible existence of granular LHM by using the Bruggeman formalism. The Wiener bounds and the Hashin-Shtrikman...

The...
