  1. 6. Mechanical characterization and modelling of iron ore pellets

    Författare :Gustaf Gustafsson; Geir Horrigmoe; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : Transportation and storage are important parts in the process chain for producers of iron ore pellets. Knowledge and optimization of these processes are very important for further efficiency progress and increased product quality. LÄS MER

  3. 7. Mechanical modeling of granite subjected to contact loading

    Författare :Hossein Shariati; Per-Lennart Larsson; Francois Hild; Mahdi Saadati; Timo Saksala; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solid Mechanics; Hållfasthetslära;

    Sammanfattning : The mechanical properties of Bohus granite subjected to contact loading is investigated based on experimental and numerical results. An elasto-plastic constitutive material model combined with a damage description is employed. The material model parameters are determined based on experimental results. LÄS MER

  4. 8. Computational model of abdominal aortic aneurysm inception and evolution

    Författare :Andrii Grytsan; T. Christian Gasser; Nicholas Hill; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aneurysm; three dimensional; elastin degradation; growth; remodeling; fluid-solid-growth model; Teknisk mekanik; Engineering Mechanics;

    Sammanfattning : Incidence of abdominal aortic aneurysm (AAA) is increasing in the aging society of the western world. Development of AAA is mostly asymptomatic and is characterized by a bulge in the abdominal aorta. However, AAA may suddenly rupture, which results in an internal bleeding associated with a high mortality rate. LÄS MER

  5. 9. Numerical studies of turbulent flames in wall-jet flows

    Författare :Zeinab Pouransari; Arne V. Johansson; Yves D'Angelo; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turbulence; combustion; direct numerical simulation; wall-jet; heat release effects; mixing scales; non-premixed flame; wall heat transfer; Teknisk mekanik; Engineering Mechanics;

    Sammanfattning : The present thesis deals with the fundamental aspects of turbulent mixing and non-premixed combustion in the wall-jet flow, which has a close resemblance to many industrial applications. Direct numerical simulations (DNS) of turbulent wall-jets with isothermal and exothermic reactions are performed. LÄS MER

  7. 10. Probabilistic high cycle fatigue models - volumetric approaches

    Författare :Salar Sadek; Mårten Olsson; Anders Ekberg; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : Fatigue is the most frequent failure mode and must be considered in a mechanical designof actual operating components. The fact that mechanical design is most often linkedwith existence of stress raisers and multiaxial time-varying stresses has in the last decadesincreased the research effort worldwide. LÄS MER
