    • Homogenization of heterogeneous, fibre structured materials 

      Fillep, S.; Mergheim, J.; Steinmann, P. (CIMNE, 2013)
      Conference report
      Open Access
      This contribution presents a multi-scale homogenization method to model fibre structured materials. On the macroscopic level textiles are characterized by a large area-to-thickness ratio, such that a discretization with ...
    • Inverse form finding with h-adaptivity and an application to a notch stamping process 

      Caspari, M.; Landkammer, P.; Steinmann, P. (CIMNE, 2017)
      Conference report
      Open Access
      The aim is to determine the optimized semi-finished workpiece geometry to its given target geometry after a forming process. Hereby, a novel approach for inverse form finding, a type of a shape optimization, is applied to ...
    • Shape optimization for anisotropic elastoplasticity in logarithmic strain space 

      Germain, S.; Steinmann, P. (CIMNE, 2011)
      Conference report
      Open Access
      This paper deals with shape optimization for anisotropic elastoplasticity in logarithmic strain space. We aim to find an appropriate undeformed configuration of a workpiece knowing in advance its deformed configuration, the ...
    • Two-scale parameter identification for heterogeneous elastoplastic materials 

      Schmidt, U.; Mergheim, J.; Steinmann, P. (CIMNE, 2011)
      Conference report
      Open Access
      The aim of this paper is to describe a method for identifying micro material parameters using only macroscopic experimental data. The FE2 method is used to model the behavior of the complex materials with heterogeneous ...
