  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. Anisotropic Muscle Phantoms for Shear Wave Elastography Assessment of the Levator Ani Muscle Properties

    Kandidat-uppsats, KTH/Medicinteknik och hälsosystem

    Författare :Bleona Koxha; Melissa Jova Martinez; [2023]
    Nyckelord :pelvic floor disorder; levator ani muscle; shear wave elastography; phantom; anisotropy; polyvinyl alcohol; bäckenbottenbesvär; levator ani muskel; shear wave elastografi; fantom; anisotropi; polyvinylalkohol;

    Sammanfattning : Pelvic floor disorder is an emerging research area and is highlighted in many pelvic floor studies. Assessment methods for this type of injury are lacking and new methods for prevention and diagnosis are needed. Pelvic floor disorders are common among women and can lead to suffering for the patient. LÄS MER

  4. 3. The Magnetic Properties and Fabrics of Upper Pleistocene Loess on La Motte, Jersey, and their Palaeoclimate Implications

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Anya Hawkins; [2022]
    Nyckelord :last glacial; magnetic susceptibility; AMS; temperature dependent magnetic susceptibility; palaeowind reconstruction;

    Sammanfattning : The island of Jersey is an interesting location for palaeoclimate reconstruction given the likely impact of variations in North Atlantic climate and European ice sheet extent during the last glacial period considering their proximal location. These last glacial climatic variations are recorded in the loess sequence from La Motte, Jersey and in order to reconstruct these changes, a detailed magnetic analysis was performed. LÄS MER

  5. 4. Simulations of anisotropic vibrations in ice induced by a laser

    Kandidat-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Victor Freedman; [2022]
    Nyckelord :ice; anisotropy; laser; freedman; molecular dynamics; simulations;

    Sammanfattning : Systems of atoms have their kinetic energy distributed between three parts: translation, rotation and vibration. These are usually kept about the same following a Maxwell distribution, but under certain circumstances, this equilibrium might break. This would lead to, for example, ice melting anisotropically.

  7. 5. The Effect Of Sub Tx Heat Treatments On The Magnetic Properties Of An Fe-based Bulk Metallic Glass

    Kandidat-uppsats, Uppsala universitet/Materialfysik

    Författare :Grunditz Jakob; [2022]
    Nyckelord :Bulk metallic glass; annealing; heat treatment; MOKE; Magnetic; Fe-based; Coercivity; Magnetic properties; Magnetic saturation; coercivity; saturation; magnetic coercivity; sub crystallization; sub Tx; Relaxation;

    Sammanfattning : Metallic glasses produced with Selective Laser Melting (SLM) often contain internal mechanic stress. This internal stress can have an impact on the magnetic properties of the material due to its connection to the magnetic anisotropy of the material. LÄS MER
