1. Validation of An Iteration Free Material Model for Paperboard (NEO)
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Hållfasthetslära; Lunds universitet/Institutionen för byggvetenskaperSammanfattning : 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. LÄS MER
2. Numerical analysis of silo discharge
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Byggnadsmekanik; Lunds universitet/Väg- och vattenbyggnad (CI)Sammanfattning : 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. LÄS MER
