    • Advanced material model for shear cutting of metal sheets 

      Gutknecht, Florian; Steinbach, Frank; Clausmeyer, Till; Tekkaya, Erman (CIMNE, 2015)
      Text en actes de congrés
      Accés obert
      A finite-element simulation of the shear cutting process is used to predict thegeometry of the cutting surface. A fully-coupled Lemaitre-type model is used in the process model for the description of the material behaviour. ...

    • Comparison of gurson and lemaitre model in the context of blanking simulation of a high strength steel 

      Gutknecht, Florian; Isik, Kerim; Clausmeyer, Till; Tekkaya, Erman (CIMNE, 2017)
      Text en actes de congrés
      Accés obert
      The process of blanking takes place in a short band with high accumulated strain undergoing various stress triaxialities. Enhanced implementations for shear and compressive loads of Gurson’s and Lemaitre’s model are directly ...
