  1. 1. Design Study of Welded Beam Bracket According to Stress Concentrations in the Weld

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : FREDRIK EKLUND; [2021]
    Keywords : Plug weld; slot weld; welded beam; welded beam bracket; welded bus chassis; Pluggsvets; svetsad balk; svetsad busschassi; svetsad ram;

    Abstract : In a bus chassis, welded connections are often preferred to other fastening techniques due to low cost and broad competence among suppliers but are usually the weakest parts due to fatigue life. Evaluation of welds is often costly in time and competence. READ MORE

  3. 2. The influence of modelling variables in FEM evaluation of fillet welded structures

    University essay from

    Author : Marko Cordasic; [2020]
    Keywords : ;

    Abstract : Valmet is a world leading company in the pulp-, paper- and energy industry and is a manufacturer of e.g. paper machines. These paper machines are largely composed of steel frames for which beams and plates are often joined by welding. READ MORE

  4. 3. 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

  5. 4. 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

  6. 5. Accuracy Study in Predicting Fatigue Life for a Welding Joint.

    University essay from KTH/Hållfasthetslära (Inst.)

    Author : Emma Fredriksson; [2015]
    Keywords : ;

    Abstract : This thesis describes a comparative study between two calculations methods for life estimates of a welding joint. The two studied methods are the Effective Notch and Linear Elastic Fracture Mechanics (LEFM). The effective notch method is today used at GKN and gives an equitable accuracy relative the work effort for the method. READ MORE
