• ATLAS of yield surfaces for strongly textured FCC polycrystals 

      Dumoulin, Stephane; Coudert, Térence; Hopperstad, Odd Sture (Peer reviewed; Journal article, 2019)
      Discrete yield surfaces for several generic texture components, including randomness, found in aluminium alloys have been generated and used to calibrate the yield function Yld2004-18p. It is generally observed that the ...
    • The hot spot in Al-rod extrusion investigated by FEM-analysis 

      Valberg, Henry Sigvart; Lefstad, Martin; Costa, André L. M. (Peer reviewed; Journal article, 2019)
      FEM-analysis is applied to study thermo-mechanical conditions in an industrial Al-rod extrusion process using long billets as stock material. In the analysis, focus is on the conditions in the hot spot present inside the ...
    • Impact of thermal history on defects formation in the last solid fraction of Cz silicon ingots 

      Lanterne, Adeline Anne; Gaspar, Guilherme Manuel Morais; Haave, Bjørn; Jomâa, Moez; Søndenå, Rune; Hupfer, Alexander; Hu, Yu; Sabatino, Marisa Di (Peer reviewed; Journal article, 2018)
      For the first time, the impact of the tail detachment on the quality of the last solid fraction of a Czochralski silicon ingot body is reported. Simulations of the thermal history were performed on CGSim software and showed ...
    • Statistical analysis of structure loss in Czochralski silicon growth 

      Sortland, Øyvind Sunde; Jomâa, Moez; M'hamdi, Mohammed; Øvrelid, Eivind Johannes; Di Sabatino Lundberg, Marisa (Peer reviewed; Journal article, 2019)
      In Czochralski monocrystalline silicon growth, structure loss (SL) is the loss of the mono-crystalline structure. It represents a significant loss of productivity. In this work, this phenomenon is investigated by statistical ...
    • Surface and bulk properties of chromium oxide: Implications for reduction by methane 

      Skjelbred, Kristin Marie; Åstrand, Per-Olof; Støvneng, Jon Andreas; Andersson, Stefan (Peer reviewed; Journal article, 2015)
      A computational method for Cr2O3 and Cr3C2 has been established based on a systematic investigation of functionals, basis sets and corrections for dispersion, self-interaction and relativistic effects. The suggested method ...
