  1. 21. Impact of Residual Stress on the Warm Pre-Stressing Effect

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Emil Danielsson; [2023]
    Nyckelord :Warm Pre-Stressing effect; Residual stress; Cleavage fracture; Ferritic Steel; Fracture mechanics; Varm förspänning; Restspänningar; Klyvbrott; Brottmekanik; Ferritiskt stål;

    Sammanfattning : Irradiation of a reactor pressure vessel (RPV) causes a shift of the ductile to brittle transition region towards higher temperature regions. In the event of a pressurized thermal shock (PTS), where the temperature drops drastically, the ductile to brittle transition region might be entered for irradiated ferritic steel. LÄS MER

  3. 22. Investigation of torsion modes in overhead traveling cranes: : Reviewing the ISO 22980 standard

    Master-uppsats, Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Författare :Simon Jens; [2023]
    Nyckelord :Overhead traveling crane; Finite element method; Frequency and experimental vibration analysis; Travers; finita elementmetod; egenfrekvensanalys; experimentell vibrationsanalys;

    Sammanfattning : Overhead cranes and rail mountings in the wall are subjected to vibrations whenlifting equipment. The purpose of this thesis is to review if the minimum frequencyvalue for cranes, according to the ISO 22986:2007 standard is conservative whendesigning overhead traveling cranes. LÄS MER

  4. 23. Effect of the ICRH Antenna Position on the Coupled Power in ITER and JET

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

    Författare :Olle Sundberg; Vincent Forsberg; [2023]
    Nyckelord :;

    Sammanfattning : Fusion energy has fascinated scientists for decades. One reason we do not see thispromising energy source powering today's society is the fact that the process requires extremeplasma temperatures. LÄS MER

  5. 24. Design of cooling-air permeable coil support

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Rozbeh Ghassemi; [2023]
    Nyckelord :Topology optimization; FEM-simulations; CFD-simulations; Material selection; Topologioptimering; FEM-simuleringar; CFD-simuleringar; Materialval;

    Sammanfattning : Coil supports are integral load-bearing components employed in generators andmotors. They serve the purpose of preventing excessive deformation and maintaininga stable position of the coils responsible for generating power and magnetic fieldswhen rotating. LÄS MER

  7. 25. Continuous Fibre Reinforcements in Injection Moulded Composites

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Författare :Erik Björkqvist; [2023]
    Nyckelord :Injection moulding; Plastics; Thermoplastics; Fibre Reinforcement; FEM; Formsprutning; Plast; Termoplast; Fiberarmering; FEM;

    Sammanfattning : The use of continuously reinforced thermoplastics have increased in recent years andoffer some significant advantages over their thermoset counterparts. The utilizationof these materials is however still limited due to the labour intensive processingand manufacturing. LÄS MER
