    • Constitutive modeling of aluminum foam including fracture and statistical variation of density 

      Reyes, Aase Gavina Roberg; Hopperstad, Odd Sture; Berstad, Torodd; Hanssen, Arve Grønsund; Langseth, Magnus (Journal article; Peer reviewed, 2003)
      An existing constitutive model applicable for aluminum foam was evaluated. The model was implemented in LS-DYNA, and several test cases were analyzed and compared to experimental data. The numerical analyses consisted of ...

    • Design and finite element simulations of aluminium foam-filled thin-walled tubes 

      Hanssen, Arve Grønsund; Reyes, Aase Gavina Roberg; Hopperstad, Odd Sture; Langseth, Magnus (Journal article; Peer reviewed, 2005)
      This paper presents experiences gained at SIMLab in modelling and design of aluminium-foam-filled tubes for structural applications. The main challenges for robust finite element simulations using explicit codes are outlined ...

    • Modeling of material failure in foam-based components 

      Reyes, Aase Gavina Roberg; Hopperstad, Odd Sture; Hanssen, Arve Grønsund; Langseth, Magnus (Journal article; Peer reviewed, 2004)
      The modeling of material failure in foam-filled beams was explored through numerical analyses with LS-DYNA. The study was based on previous physical tests on bending of square aluminum extrusions filled with aluminum foam. ...
