    • Homogenization and modeling of fiber structured materials 

      Fillep, Sebastian; Steinmann, Paul (CIMNE, 2011)
      Conference report
      Open Access
      For the mechanical modeling and simulation of the heterogeneous composition of a fiber structured material, the material properties at the micro level and the contact between the fibers have to be taken into account. The ...

    • Modeling the porous and viscous responses of human brain tissue behavior 

      Comellas Sanfeliu, Ester; Budday, Silvia; Pelteret, Jean-Paul; Holzapfel, Gerhard A.; Steinmann, Paul (2020-09-01)
      Article
      Open Access
      The biomechanical characterization of human brain tissue and the development of appropriate mechanical models is crucial to provide realistic computational predictions that can assist personalized treatment of neurological ...

    • Plastic dislocation and incompatibility density as indicators for residual stresses 

      Landkammer, Philipp; Steinmann, Paul (CIMNE, 2019)
      Conference report
      Open Access
      Residual stresses in forming simulations are typically investigated by analyzing the remaining stress state after removing all external loadings. However, the generation of the stress state during forming remains unknown. ...

    • Poro-viscoelastic effects during biomechanical testing of human brain tissue 

      Greiner, Alexander; Reiter, Nina; Paulsen, Friedrich; Holzapfel, Gerhard A.; Steinmann, Paul; Comellas Sanfeliu, Ester; Budday, Silvia (2021-08-17)
      Article
      Open Access
      Brain tissue is one of the softest tissues in the human body and the quantification of its mechanical properties has challenged scientists over the past decades. Associated experimental results in the literature have been ...

    • Poro-viscoelastic material parameter identification of brain tissue-mimicking hydrogels 

      Kainz, Manuel; Greiner, Alexander; Hinrichsen, Jan; Kolb, Dagmar; Comellas Sanfeliu, Ester; Steinmann, Paul; Budday, Silvia; Terzano, Michele; Holzapfel, Gerhard A. (Frontiers Media SA, 2023-04-10)
      Article
      Open Access
      Understanding and characterizing the mechanical and structural properties of brain tissue is essential for developing and calibrating reliable material models. Based on the Theory of Porous Media, a novel nonlinear ...
