  1. 1. Modelling, Evaluation and Assessment of Welded Joints Subjected to Fatigue

    University essay from Linköpings universitet/Mekanik och hållfasthetslära

    Author : Prajeet Rajaganesan; [2020]
    Keywords : Welded joints; Fatigue Assessments; Hot Spot method; Python Automation; Post-processing; Abaqus;

    Abstract : Fatigue assessment of welded joints using finite element methods is becoming very common. Research about new methods is being carried out every day that show a more accurate estimation of the fatigue life cycle than the previous ones. READ MORE

  3. 2. Thermo-Mechanical Fatigue Assessment of Marine Boiler : Using linear Finite Element Analyses

    University essay from Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Author : Adefemi Samuel Alagbada; [2020]
    Keywords : Marine Boiler; FEA; Thermo-mechanical Loading; LEFM; Paris law; Flaws; RAO.;

    Abstract : This thesis is on fatigue crack growth assessments of a thermomechanical loaded Marine Boiler- Sunrod CPDB12. The installation position of the marine boiler in the ship in relation to its fatigue life under mode 1 loading is investigated. READ MORE

  4. 3. Analysis of uncertainties in fatigue load assessment : a study on one Kaplan hydro turbine during start operation

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Annica Gustafsson; [2019]
    Keywords : Hydropower; Hydro turbine runner; Uncertainty analysis; Fatigue load; Fatigue damage; Propagation of uncertainty.; Vattenkraft; Löphjul; Osäkerhetsanalys; Utmattning; Delskada; Fortplantning av osäkeheter.;

    Abstract : In the future, hydropower plants are expected to operate more flexibly. This will lead to a more varied operation of the turbine and the generator, such as more start and stop in order to stabilise the frequency in the grid. Studies show that these transient operations are more costly in terms of fatigue degradation, i.e. READ MORE

  5. 4. Fatigue and dynamics of secondary beams in steel railway bridges

    University essay from KTH/Bro- och stålbyggnad

    Author : Peeter Kanter; [2014]
    Keywords : Bridge; Fatigue; Assessment; Dynamics;

    Abstract : Many steel railway bridges in Europe are older than 50 years whilethey are subjected to higher loads than they were originally designedfor. As many of these bridges are approaching the end of their designlife it is crucial to carry out accurate fatigue assessments in order toensure their safety and keep them in service. READ MORE
