  1. 1. Estimation of Fatigue Life for Welded Gears Using LEFM

    Master-uppsats, KTH/Hållfasthetslära (Avd.)

    Författare :Richard Tynander; [2017]
    Nyckelord :;

    Sammanfattning : The aim of this thesis is to estimate the high cycle fatigue life of welds using finite element methods and liner elastic fracture mechanics (LEFM). Develop a new method of calculating the fatigue life that can replace the old method in use today at GKN Driveline. This is a continuation of an earlier master thesis1. LÄS MER

    Sammanfattning : The aim of this study was to examine if simplified linear analysis can be used to capture the complex and non-elastic behaviour that filled rubber exhibits. Linear analysis includes both linear elastic material models and a linear solving technique. LÄS MER

  4. 3. FEM‐modeller för expansionsanalys av piplines

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Cristina Lindholm; [2007]
    Nyckelord :;

    Sammanfattning : REINERTSEN AS performs expansion and buckling analyses of pipelines using ANSYS, a finite element modelling and analysis tool. In an expansion analysis the pipeline is modelled with thin ‐ walled pipe elements called PIPE20 which allows plastic deformation. LÄS MER
