  1. 1. Investigation of asphalt compaction in vision of improving asphalt pavements

    Författare :Ehsan Ghafoori Roozbahany; Manfred N. Partl; Gabriele Tebaldi; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cold asphalt pavement joints; asphalt joint laboratory production; IDT joint evaluation; DTT joint evaluation; 4PB joint evaluation; joints FEM analysis. Discrete Element Modeling DEM ; X-ray Computed Tomography CT ; Compaction Flow Test CFT ; Compactability;

    Sammanfattning : Asphalt joints are potentially weakest parts of every pavement. Despite of their importance, reliable tools for measuring their mechanical properties for design and performance assessments are still scarce. LÄS MER

  4. 3. Muscular forces from static optimization

    Författare :Sofia Heintz; Anders Eriksson; Elena Gutierrez-Farewik; Anton Arndt; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; movement analysis; muscle forces; static optimization; Other engineering mechanics; Övrig teknisk mekanik;

    Sammanfattning : At every joint there is a redundant set of muscle activated during movement or loading of the system. Optimization techniques are needed to evaluate individual forces in every muscle. The objective in this thesis was to use static optimization techniques to calculate individual muscle forces in the human extremities. LÄS MER

  5. 4. The fixation of joint prostheses. Aspects on mechanics and biology

    Författare :Ulrik Hansson; Lund Ortopedi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; radiostereometry; histology; interface; micromotion; knee; joint replacement;

    Sammanfattning : Abstract: In the interface, between implant and bone or between the cement and bone, there will develop some amount of fibrous tissue. The synovial fluid, the synovium, the cartilage and the subchondral bone from the non-replaced knee compartment that had been exposed to wear particles were studied by histological analyses. LÄS MER

  7. 5. Interfibre Joint Strength under Mixed Modes of Loading

    Författare :Mikael S. Magnusson; Sören Östlund; Kaarlo Niskanen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Interfibre joint strength; fibre-fibre cross; paper mechanics; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : The load carrying capacity of interbre joints are one of the key entities for build-up of strength inpaper materials. In order to gain insight in how to tailor the macroscopic properties of such materialsby chemical and/or mechanical treatments at a microscopic level, direct measurement of individualbre{bre crosses are typically performed.
