    Nyckelord :Master thesis; shell boiler; corrosion; creep; validation; EN12953; European standard; Examensarbete; eldrörspanna; korrosion; kryp; validering; EN12953; europeisk standard;

    Sammanfattning : Shell boilers used in Sweden and Europe has to be certified before being used. Kiwa Sweden performs the role as an accredited third party for control services within most industries in Sweden. Kiwa Sweden has acquired an analysis program called  sPEeD12953 from the danish company Danish Exergy Technology (DXT). LÄS MER

  3. 2. Evaluation of Crack Depth Meter - An investigation of the crack depth meters possibilities and limitations for commonly occurring damage mechanisms

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Alfred Norberg; [2023]
    Nyckelord :Crack depth measurement; RMG 4015; ACPD; Damage Mechanism; Evaluation; FEM Simulation; Sprickdjupsmätning; RMG 4015; ACPD; Skademekanism; Utvärdering; FEM-simulering;

    Sammanfattning : In this master thesis, the accuracy of the crack depth meter RMG 4015 was evaluated for different types of cracks with various damage mechanisms. In total, 61 crack depth measurements were conducted with the crack depth meter on 56 cracks which were located in the 23 different test pieces supplied by Kiwa. LÄS MER

  4. 3. Approximating Damping Coefficient of Bolted Joints using the Finite Element Method

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Abhiroop Chatterjee; [2023]
    Nyckelord :;

    Sammanfattning : Bolted joints are important due to their energy dissipation property in structures,but the damping mechanism is also highly nonlinear and localized. The goal ofthis thesis is to develop an accurate method for modeling bolted joint dampingin large structures using finite element (FE) software. LÄS MER

  5. 4. Experimental Testing of EPS-foam

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Carl Göransson; Erik Arnald; [2023]
    Nyckelord :Solid Mechanics; EPS; Experimental testing; Hållfasthetslära; EPS; Experimentell testning;

    Sammanfattning : The aim of this master thesis was to investigate the mechanical properties of ExpandedPolystyrene (EPS) through experimental testing. The strain was measured on thespecimen’s surface with Digital Image Correlation (DIC), in order to investigate howthe first principal strain at fracture initiation depends on the loading of the material.
