  1. 1. In-plane bi-axial testing of thin paper

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Asad Ali; Danay Michael; [2022]
    Nyckelord :;

    Sammanfattning : During its lifetime, a beverage package is subjected to a complex loading history where the loading, in general, is multiaxial. Hence, to optimize the performance of the package, knowledge of the material’s anisotropic multi-axial deformation and subsequent failure is necessary. LÄS MER

  3. 2. Design of column bases concerning bending and shear nibs

    M1-uppsats, KTH/Byggteknik och design

    Författare :Rodi Kay; [2021]
    Nyckelord :Column bases; Pelarfötter;

    Sammanfattning : The purpose of the thesis is to find out how to design column bases with conventional methods presented by European standards and codes, but above all from the Steel Construction Institute's handbook on structural joints and compare it with finite element analyses. However, today there are no good instructions for how column bases exposed to multiaxial bending should be designed, where assumptions based on structural mechanics also was compared with computer tools.

  4. 3. Comparison of Fatigue Life Evaluation Methods

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Louise Hedberg Lundblad; Anna Lund; [2021]
    Nyckelord :Solid Mechanics; Fatigue; Time history methods; Spectral methods; Truck components; Road induced vibrations; Hållfasthetslära; Utmattning; Tidshistoriksmetoder; Spektrala metoder; Lastbilskomponenter; väginducerade vibrationer;

    Sammanfattning : The aim of this thesis is to investigate a selected set of fatigue life calculation methods and evaluate if they are suitable for fatigue life estimation of truck components at Scania. Failure due to fatigue can be cause by road induced vibrations, which is an inevitable phenomenon trucks are exposed to. LÄS MER

  5. 4. Estimation of fatigue life by using a cyclic plasticity model and multiaxial notch correction

    Master-uppsats, Linköpings universitet/Mekanik och hållfasthetslära

    Författare :Nils Johansson; [2019]
    Nyckelord :Multiaxial load; fatigue; notch; elastic-plastic; stress-strain; non-proportional load; incremental Neuber; damage parameter;

    Sammanfattning : Mechanical components often possess notches. These notches give rise to stress concentrations, which in turn increases the likelihood that the material will undergo yielding. The finite element method (FEM) can be used to calculate transient stress and strain to be used in fatigue analyses. LÄS MER

  7. 5. Continuous Time Fatigue Modelling for Non-proportional Loading

    Master-uppsats, Linköpings universitet/Mekanik och hållfasthetslära

    Författare :Sajjan Gundmi Satish; [2019]
    Nyckelord :Multiaxial Fatigue Loading; Fatigue Analysis; Continuous Time fatigue model; Endurance Surface; Rainflow Counting; Cyclic loading; Cycle Counting; Damage Evolution; High-cycle fatigue; Non-proportional loading;

    Sammanfattning : Fatigue analysis is a critical stage in the design of any structural component. Typically fatigue is analysed during post-processing, but as the size of the analysed component increases, the amount of data stored for the analysis increases simultaneously. LÄS MER
