• Assessment of yield and fracture criteria using shear and bending tests 

      Reyes, Aase Gavina Roberg; Eriksson, Magnus; Lademo, Odd-Geir; Hopperstad, Odd Sture; Langseth, Magnus (Journal article; Peer reviewed, 2009)
      This article deals with the calibration of a fracture criterion that has been implemented in a material model in LS-DYNA. The failure process in thin-walled metallic materials is complex and often due to interaction between ...
    • Validation study of failure prediction in crash analysis 

      Reyes, Aase Gavina Roberg; Dørum, Cato; Hopperstad, Odd Sture; Langseth, Magnus; Lademo, Odd-Geir; Eriksson, Magnus (Chapter, 2008)
      Modeling of plastic deformation and failure is critical in crash analysis. In the present paper, we have studied one approach to represent instabilities and damage evolution in non-linear finite element analyses of forming ...
