  1. 1. Evaluation of pretension losses in heated screw joint

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Joel Svensson; [2022]
    Nyckelord :screw joint; clamping force; thermal load;

    Sammanfattning : The heated flow within the silencers of heavy transport vehicles can easily reach temperatures of hundreds of degrees Celsius. The thermal loads can cause problems for certain components on a silencer. LÄS MER

  3. 2. Evaluation of welding joint methods for a prismatic battery cell module

    Master-uppsats, Lunds universitet/Innovation

    Författare :William Hellingwerf; [2021]
    Nyckelord :Aluminium welding methods; Battery module; Prismatic cell; Weld strength; Weld analysis; Weld temperature simulation; Technology and Engineering;

    Sammanfattning : Prismatic battery cells swell due to a number of different factors, such as state of charge, temperature and irreversibly with charge cycling. Cell health can be improved by restricting the swelling of the cell, and therefore, the container which holds the cells, the module, should be able to restrict the swelling, and thus withstand the force exerted by the cells.

  4. 3. Modelling of Laser Welding of Aluminium using COMSOL Multiphysics

    Master-uppsats, KTH/Materialvetenskap

    Författare :Jie Chen; [2020]
    Nyckelord :laser welding process; aluminium alloy; thermal-mechanical; COMSOL Multiphysics; hot cracking; thermal model; CFD model; mechanical model; Marangoni effect; lasersvetsningsprocess; aluminiumlegeringar; termisk-mekanisk; COMSOL-flerfysik; hetsprickning; termisk modell; CFD-modell; mekanisk modell; Marangoni-effekt;

    Sammanfattning : This thesis presents a modelling approach of laser welding process of aluminium alloy from the thermo-mechanical point of view to evaluate the occurrence of hot cracking based on simulation results and relevant criteria. The model was created stepwise in COMSOL Multiphysics, starting with the thermal model where heat conduction of solid and liquid phase was computed. LÄS MER

  5. 4. Assessment of creep damage in Fe-Ni-Cr alloys

    Master-uppsats, KTH/Hållfasthetslära (Avd.)

    Författare :Frans Sorsh; [2019]
    Nyckelord :;

    Sammanfattning : It is only a matter of time before components working in high temperature environments fail due to creep. Design for creep is therefore of vital importance to maximize the lifetime of components and reduce costs that may arise from maintenance and replacement of components. LÄS MER

  7. 5. Numerical simulation of residual stresses in a weld seam : An application of the Finite Element Method

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

    Författare :Maciej Maczugowski; [2017]
    Nyckelord :Finite element method; residual stresses; temperature distribution; fatigue life; weld power; time step; T-joint weld model; Butt weld model.;

    Sammanfattning : Articulated haulers are fundamental equipment to transport material. The load carrying structure on a hauler consists mainly of welded frames. During welding of the frames high residual stress will be introduced. These stresses may have a significant impact on the fatigue life of the frames. LÄS MER
