  1. 1. Validation of An Iteration Free Material Model for Paperboard (NEO)

    University essay from Lunds universitet/Hållfasthetslära; Lunds universitet/Institutionen för byggvetenskaper

    Author : Samuel Thomas Staines; [2022]
    Keywords : Paperboard; orthotropic; Constitutive equilibrium free; Non-linear; Curve fit constitutive relation; switch-wise history dependence; total formulation; explicit constitutive relation; In-plane; Elastic-plastic; Technology and Engineering;

    Abstract : The NEO model, developed by Lindström (2019) for paperboard, is a non-linear material model that utilizes empirically based constitutive relations with switches to mimic elastic-plastic responses. Due to the explicit definition of the constitutive relations, the NEO model does not require a constitutive equilibrium loop. READ MORE

  3. 2. Numerical analysis of silo discharge

    University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Väg- och vattenbyggnad (CI)

    Author : John Brown; [2008]
    Keywords : Inner tube; Iron ore pellets; Silo; Granular flow; FEM; ABAQUS.; Technology and Engineering;

    Abstract : A silo discharge with a bulk material consisting of iron ore pellets is studied. The silo is about 65 meters high and 38 meters wide. The quality of pellets decreases when they are exposed to high stresses while moving. The stresses are therefore not allowed to exceed a certain threshold. READ MORE
