1. Validation of Finite Element Model of a Tetra Pak Package
University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknikAbstract : There is a high dependency on accurate finite element models in the packaging industry for concept selection, design and virtual validation of packages. One of themost used materials for these packages is High-Density Polyethylene (HDPE). Thismaterial is highly anisotropic, strain rate dependent and has different behavior intension and compression.

2. Material Characterization and Blade Impact Simulation
University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikAbstract : Blades used on brushcutters and lawn mowers are subjected to a wide variety of working conditions. Besides continuous loads from cutting grass, the blades are also subjected to accidental impacts of branches, stones and structures. READ MORE

3. Linear Impact of Bicycle Helmet – Experimental Testing and FE-modelling
University essay from KTH/HållfasthetsläraAbstract : The aim with this master thesis was to set up a FE-simulation of an impact test of a bike helmet in LS-DYNA that correlates well with the peak acceleration score of a real life impact test. Furthermore, a parametric study has been performed in LS DYNA to investigate the robustness of the model, as well as to see which parameters have a great influence on the peak acceleration score.

4. Microstructural evolution of ice under simple shear deformation
University essay from Göteborgs universitet/Institutionen för geovetenskaperAbstract : To investigate microstructure in ice deformed under simple shear conditions experiments were performed with artificial polycrystalline ice and natural ice samples form Vatnajökull glacier in Iceland. A new deformation apparatus was tested and results from deformation were compared to literature to validate the method. READ MORE

5. Material parameter identification of a thermoplastic using full-field calibration
University essay from Linköpings universitet/Mekanik och hållfasthetsläraAbstract : Finite element simulation of thermoplastic components is gaining importance as the companies aim to avoid overdesign of the components. Cost of the component can be minimized by using an adequate amount of material for its application. READ MORE
