  1. 21. 3D FE Simulations of Resistance Spot Welding

    University essay from KTH/Hållfasthetslära (Inst.)

    Author : David Lövenborn; [2016]
    Keywords : ;

    Abstract : Resistance spot welding (RSW) is thedominant joining technology in theautomotive industry. This is due to its lowcosts and high efficiency. READ MORE

  3. 22. Fracture Simulation of Electrofusion Joining.

    University essay from KTH/Hållfasthetslära (Inst.)

    Author : Amir Alizadeh; [2015]
    Keywords : ;

    Abstract : This Master thesis investigates mechanical failures of electrofusion joints. This type of joints are used for weld high density polyethylene pipe systems where tting and pipe will be welded together by the heat caused by the resistance of the copper cables to electric current.

  4. 23. Simulation of laser welding in sandwich rocket nozzle

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

    Author : Filip Elfving; [2015]
    Keywords : FEM; Sandwich; T-joint; residual deformations; residual stresses; Laser;

    Abstract : This bachelor thesis has been carried out at GKN Aerospace. GKN is a member of European Space Agency, designing and manufacturing rocket-nozzles for the Ariane rockets. The manufacturing process entails many welds. Weld-simulations have been made to investigate stresses and plastic strains on simplified geometries. READ MORE

  5. 24. Weld head motion control of girth and tubular joint welding simulations in LS-DYNA

    University essay from Avd för maskinteknik

    Author : Andreas Segerstark; [2013]
    Keywords : FINITE ELEMENT ANALYSIS; LS-DYNA; LS-PREPOST; MOVING HEAT SOURCE; GIRT WELDING; TUBULAR JOINT WELDING.;

    Abstract : The basis for performing a thermo-mechanical staggered coupled heat source analysis of a welding simulation is implemented into LS-DYNA. In this report, three methods for initiating the heat source’s mechanical motion during girth and tubular joint welding are developed and evaluated. READ MORE

  6. 25. 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
