  • A Method for suppresion of defects in zigzag bending of sheet metal 

    Tanabe, Shota; Mochizuki, Takahiro; Abe, Hiroyuki; Kuboki, Takashi (CIMNE, 2015)
    Text en actes de congrés
    Accés obert
    This study presents methods for suppression of defects observed in zigzag bending of sheet-metal or plate. This type of bending is widely used in industry for manufacturing structural parts in automobiles. Although it is ...
  • 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. ...
