  1. 1. 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

  3. 2. 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

  4. 3. Analysis of welding in comparable steel grades : Influence of steel grade on the welding process

    University essay from Karlstads universitet/Avdelningen för maskin- och materialteknik

    Author : Stefan Andersson; [2014]
    Keywords : Welding; joining; steel;

    Abstract : This master thesis is written to examine the influence of different low carbon steel sheet materials on the GMAW welding process. During welding the properties of the base material influence the productivity of the welding process. READ MORE

  5. 4. Weld optimization with new Low Temperature Transformation fillermaterials

    University essay from KTH/Industriell produktion

    Author : Gustav Schmidt; [2013]
    Keywords : ;

    Abstract : In this study, evaluation of typical weld geometry, residual stresses and fatigue properties of two new LTT consumables have been performed. The literature survey discusses the topics of LTT consumables regarding fatigue life, chemical composition, dilution, crack phenomena and fatigue crack repair, impact toughness, weld residuals stress and weldgeometry.

  6. 5. Effect of material grade on fatigue strength and residual stresses in high strength steel welds

    University essay from KTH/Lättkonstruktioner

    Author : Wasim Asgher; [2012]
    Keywords : Fatigue Strength; Fillet Welded Joints; Effective Notch Method; Residual Stress Simulation.;

    Abstract : This thesis work is concerned with effect of material grade on fatigue strength of welded joints. Fatigue strength evaluation of welded joints in as welded and post weld treated condition was carried out with effective notch method. Results of peak stress method have also been compared with those of effective notch method for as welded joints. READ MORE
