  1. 16. Including Finite Larmor Radius Effects on RF Heating of Fusion Plasmas using Weak-Form Contributions in COMSOL

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Jonas Christ; [2022]
    Nyckelord :plasma; fusion; RF; radio frequency; IBW; FW; ion Bernstein wave; fast wave; simulation; FEM; finite element method; Taylor; Taylor expansion; COMSOL; MATLAB; FLR; finite larmor radius; magnetized plasma; hot plasma; thermal plasma; plasma; fusion; radiofrekvens; simulation; FEM; finita elementmethod; Taylor; Taylorutveckling; COMSOL; MATLAB; FLR; ändliga Larmorradie-effekter;

    Sammanfattning : In a fusion plasma, the ions have to be heated to reach fusion relevant temperatures. One possibility is to launch an electromagnetic wave in the radio frequency band into the plasma. This wave can resonate with the ions at their cyclotron frequency and hence, the method is called ion cyclotron resonance heating. LÄS MER

  3. 17. Parametrisk modellering av pålgrupper: Koppling mellan Grasshopper och Sofistik

    M1-uppsats, KTH/Byggteknik och design

    Författare :Kimm Nordvall; Mikael Stenberg; [2022]
    Nyckelord :FEM; Finite elements; Parametric modelling; Sofistik; Grasshopper; Rhinoceros; Piling; FEM; Finita element; Parametrisk modellering; Sofistik; Grasshopper; Rhinoceros; Pålgrundläggning;

    Sammanfattning : Pålgrundläggning är en vanlig metod vid grundläggning där sämre markförhållanden råder. För broaroch andra anläggningskonstruktioner måste stora laster tas i beaktande, både horisontella ochvertikala. LÄS MER

  4. 18. In-plane bi-axial testing of thin paper

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Asad Ali; Danay Michael; [2022]
    Nyckelord :;

    Sammanfattning : During its lifetime, a beverage package is subjected to a complex loading history where the loading, in general, is multiaxial. Hence, to optimize the performance of the package, knowledge of the material’s anisotropic multi-axial deformation and subsequent failure is necessary. LÄS MER

  5. 19. Assessment of ice loads on piled structures based on local conditions

    Master-uppsats, KTH/Betongbyggnad

    Författare :Astrid Lindblom; Elin Ånger; [2022]
    Nyckelord :Ice loads; Local conditions; Structural design; Piled structures; Islaster; Lokala förhållanden; Dimensionering; Pålade konstruktioner;

    Sammanfattning : This master report studies structural design methods for ice loads and the impact of local conditions. Ice loads occur due to ice movements or expansion of the ice sheet. Specifically, this study analyses ice loads on piled structures and ten different design methods and handbooks to calculate the ice load. LÄS MER

  7. 20. Design of passively loaded specimen for constant KI during crack growth

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Liisa Tofferi; [2021]
    Nyckelord :constant KI; passively loaded specimen; konstant KI; passivt belastad provstav;

    Sammanfattning : Passive loading of a specimen is a relatively cheap method to use in fracture mechanical testing compared to an actively loaded specimen. For stress corrosion cracking testing it is easier to use a passively loaded specimen since the specimen easily can be placed in a specific corrosive environment. LÄS MER
