1. Validation of An Iteration Free Material Model for Paperboard (NEO)
University essay from Lunds universitet/Hållfasthetslära; Lunds universitet/Institutionen för byggvetenskaperAbstract : 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

2. Investigation of case hardened steel subjected to torsion: An experimental and numerical elastic-plastic material study
University essay from KTH/HållfasthetsläraAbstract : There is currently a knowledge gap regarding the plastic material properties of many steel types that Atlas Copco use in their high torque power tools. This makes it difficult to fully utilise the capabilities of the Finite Element Method (FEM) to aid the developmental process. READ MORE

3. In-plane bi-axial testing of thin paper
University essay from KTH/HållfasthetsläraAbstract : During its lifetime, a beverage package is subjected to a complex loading history where the loading, in general, is multiaxial. Hence, to optimize the performance of the package, knowledge of the material’s anisotropic multi-axial deformation and subsequent failure is necessary. READ MORE

4. Strain rate-dependent mechanical properties of high-density polyethylene(HDPE)
University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknikAbstract : In today’s packaging industry HDPE is widely used and correct understanding of itsproperties and how to model them is of vital importance. HDPE is a semi-crystallinepolymer with a known strain rate dependence, that is a higher yield and lower strainto failure at higher strain rates. READ MORE

5. Tensile strength reduction for insufficient thread engagement A FEM study of a wall-shoe assembly
University essay from KTH/HållfasthetsläraAbstract : The purpose of this master thesis is to determine whether or not it exist, a model that can describethe reduction in strength, due to missing threads in a bond between a bolt and nut. And how thereduction in strength might effect a wall-shoe assembly, used to connect a wall to another wall or aconcrete base plate. READ MORE
