  1. 6. Fillet Weld Fatigue Lifetime : Parametric Finite Element Analysis

    University essay from Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Author : Vishal Singaravadivelu; Sai Krishna Vemulapalli; [2020]
    Keywords : Fatigue Strength; Fillet weld; Weld toe radius; Effective notch stress method; Parametric Finite Element Analysis - PFEA;

    Abstract : The fatigue life time of welded components is the dominant factor at the design of mechanical and automotive structures and components where fatigue failure has a crucial outcome in use of fillet welded structures and it commences mostly from the weld toe and propagate to the parent material or even to the weld root area. Fillet welds are the imperative type of weld used in many industries because of the geometry and fabrication cost of the structure. READ MORE

  2. 7. Estimation of fatigue life by using a cyclic plasticity model and multiaxial notch correction

    University essay from Linköpings universitet/Mekanik och hållfasthetslära

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

    Abstract : 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. READ MORE

  3. 8. Investigating aluminum plate with different geometrical shape by using DIC tension test

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Peng Yang; [2019]
    Keywords : Sheet metal; DIC method; Stress concentration; Notch shape;

    Abstract : This subject mainly uses Aluminum sheet metal material as the research object which is used in Volvo XC90 door, the elastic plasticity deformation within the different material angles and notch shape investigated with MTS tensile test equipment under uniaxial tension. The local strain curve studied by using DIC method to obtain the conventional physical quantity. READ MORE

  4. 9. Fatigue Life Analysis of Weld Ends : Using FE-Calculations and Mechanical Testing

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Victor Ljungdahl; [2018]
    Keywords : Comparison; Effective notch method; Testing; Weld End; Jämförelse; Effective notch metoden; Provning; Svetslut;

    Abstract : Fatigue life estimation of welds is a complex issue since the characteristics of each weld are unique depending on load case, geometry and properties. Fatigue life estimation on weld ends is limited and often the weakest point of a weld. READ MORE

  5. 10. Stress Analysis of Different Shaped Holes on a Packaging Material

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Venkata Naga Sai Krishna Janardhan Parimi; Vamsi Eluri; [2016]
    Keywords : ABAQUS; Crack Initiation; EPFM; Geometric function; Hole shapes; LDPE; LEFM; Mode I tensile loading;

    Abstract : In packaging industries, the demand for usage of Low Density Poly Ethylene foil is of profound interest. In the past, research was carried out on finite and infinite plates with varying crack lengths but having constant crack width. In this thesis, a detailed analysis on crack initiation is carried out on finite plates by varying width of the hole. READ MORE
