  1. 1. Validation of Finite Element Model of a Tetra Pak Package

    Uppsats för yrkesexamina på avancerad nivå, Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Warsame Mohamed Ali; Abdullahi Abdi Hashi; [2023]
    Nyckelord :Abaqus; HDPE; Package testing; Validation; Abaqus; HDPE; Pakettestning; Validering;

    Sammanfattning : 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.

  3. 2. Petrophysical Properties of Rocks in Central Kiruna Mining District, Sweden

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Simon Peter Dagbui; [2023]
    Nyckelord :Kiruna mining district; Common earth model; petrophysics; density; AMS; complex electrical resistivity; NRM; magnetization; IOA; Kirunavaara Mineralization;

    Sammanfattning : High economic and metallogenic significance of northern Norrbotten ore district in Sweden which hosts Kiruna mining district makes it a very important ore district in the world. Northern Norrbotten ore district contributes a combined 90 percent of iron production in Europe. LÄS MER

  4. 3. Electron Backscatter Diffraction (EBSD) Analysis and Predicted Physical Properties of Shocked Quartz from the Chicxulub Impact Crater, Mexico

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Erina Prastyani; [2022]
    Nyckelord :EBSD; SEM; shocked quartz; quartz; CPO; seismic velocity; anisotropy; Chicxulub; impact crater; pole figures; MTEX toolbox; microstructural features; planar deformation feature; planar fracture; feather features;

    Sammanfattning : As one of the most common minerals in crustal rocks, quartz has been widely used as an indicator for shock metamorphism. Shocked quartz is found in the Chicxulub impact crater, an impact crater that has been linked to the Cretaceous-Tertiary extinction ~66 million years ago. LÄS MER

  5. 4. Continuum damage modeling of delamination in paperboard

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för byggvetenskaper; Lunds universitet/Hållfasthetslära

    Författare :Erik Jakobsson; [2021]
    Nyckelord :Creasing; Folding; MD-direction; EB material model; LS-Dyna; eGISSMO; Technology and Engineering;

    Sammanfattning : This work concerns the creasing and folding of a continuum paperboard material model developed by Eric Borgqvist. Creasing is an operation that induces permanent deformation in the material, undertaken for the folding to be performed along a straight fold line without any in-plane cracks. LÄS MER

  7. 5. Event Geometry and Anisotropic Flow in Proton-Proton Collisions

    Kandidat-uppsats, Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Författare :Johannes Holst; [2021]
    Nyckelord :high energy physics; particle physics; proton; collision; quark-gluon plasma; flow; anisotropy; anisotropic flow; elliptic flow; initial state; geometry; eccentricity; gaussian; cms; alice; lhc; Physics and Astronomy;

    Sammanfattning : We seek to better understand the relationship between an anisotropic distribution of partons in the initial state of pp-collisions and the amount of elliptic flow. We do this through the implementation of a new model that is based in generating positions for multiparton interactions from the uneven volume created by the overlap of two Gaussians. LÄS MER
