  1. 1. FE-Modelling of Composite Girder tests

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Holger Berggren; Bergstedt Ola; [2024]
    Nyckelord :shear connector; post-installed; coiled spring pins; composite girder; partial composite action; finite element method;

    Sammanfattning : Many of the existing steel-concrete bridges may need to be strengthened, as heavier vehicles areallowed on the Swedish roads. These bridges could possibly be strengthened by post-installingshear connectors. The shear connectors may enhance the load-bearing capacity through a higherdegree of composite action between the steel and concrete interface. LÄS MER

  3. 2. Method Development & Analysis of Seals using FEM

    Master-uppsats, KTH/Maskinkonstruktion

    Författare :Lovisa Svanborg Östlin; [2023]
    Nyckelord :FEM; guidelines; hyperelastic materials; hyperelastic material models; method development; seals; FEM; riktlinjer; hyperelastiska material; hyperelastiska materialmodeller; metodutveckling; tätningar;

    Sammanfattning : Hyperelasticity is a significant property of rubber, taken advantage of in engineering applications. A common application is the use of seals to prevent fluid transfer (liquid or gas) between solid regions. Volvo CE is often depending on external supplier when developing seals. LÄS MER

    Sammanfattning : This report formulates the boundary conditions and discretization method for conducting a simulation of heat with liquids and solids through the finite element method. It introduces the reader to the movement that is due today with optimization of heat transport and mitigation generally described as the fourth generation of district heating. LÄS MER

  5. 4. 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. 5. Visualization, modeling and consequences of residual stresses in glass frit sealing of a UV light source

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Mikrosystemteknik

    Författare :Vilma Hurtigh Grabe; [2023]
    Nyckelord :bonding; micro system; glass frit; sealing; finite element; modeling; glass; mikrosystem; sammanfogning; glasfog; fog; finita element; modellering; glas;

    Sammanfattning : PureFize Technologies AB develops and manufactures a broadband ultraviolet (UVC) light technology device that is mercury-free and based on nanotechnology, using the principle of field emission. The light source is made of Ti and glass, which are hermetically bonded, using a low-temperature glass frit, at elevated temperatures. LÄS MER
