  1. 1. Fatigue strength assessment of post weld improved welded joints

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Veronika Nerbe; [2023]
    Keywords : Mechanics; solid mechanics; lightweight structures; hfmi; weld; Mekanik; hållfasthetslära; lättkonstruktioner; hfmi; svets;

    Abstract : In this thesis work a literature survey is done to collect published data for T-welded joints with a thickness of 5-12 mm, produced in high strength steel and treated with HFMI. In addition to this, large structures are researched. READ MORE

  3. 2. Irradiation Embrittlement on a Core Shroud from Decommissioned BWR

    University essay from KTH/Fysik

    Author : Åsa Bjåland; [2023]
    Keywords : hardness; Vickers hardness test; ATT; yield strength; irradiation embrittlement; welds; hårdhet; Vickers hårdhetstest; ATT; sträckgräns; bestrålningsförsprödning; svetsar;

    Abstract : Irradiation embrittlement is a problematic issue for internal structures, such as acore shroud, in a light water reactor. It is characterized by decreased ductility andtoughness, and increased yield strength and hardening due to increased dislocations. READ MORE

  4. 3. Projection Nut Welding to High- and Ultra-high Strength Steels

    University essay from KTH/Hållfasthetslära

    Author : Love Englund; [2023]
    Keywords : mechanics; solid mechanics; material mechanics; welding; resistance welding; projection welding; nut welding; high strength steel; ultra high strength steel; uhss; coated boron steel; mekanik; hållfasthetslära; materialvetenskap; svetsning; motståndssvetsning; projektionssvetsning; muttersvetsning; belagt borstål;

    Abstract : In an effort to increase the fuel efficiency of cars more widespread use of higher strength steels is seen for their high strength-to-weight ratio. Thesesteels are more limited in their formability and tendency to harden than conventional steels, complicating manufacturing. READ MORE

  5. 4. Wheel Loader Rear Axle Mounting for Weld Deformations : Exploration and Evaluation of Alternative Mounting Methods

    University essay from Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Author : Frans Forsberg; [2023]
    Keywords : Product Development; Weld Deformation; Design for Manufacturing; Reverse Engineering; 3D-scanning; Wheel Loader;

    Abstract : Welded structures susceptible to weld deformations require sequent processing to allow for mounting of precision components. This thesis includes a case study of the rear axle mount on a Volvo L220 wheel loader. READ MORE

  6. 5. Methodology for Obtaining S-N Curves using Fatigue Testing and Static FEA

    University essay from Jönköping University/JTH, Material och tillverkning

    Author : Filip Anderfelt; David Äse; [2022]
    Keywords : Fatigue; Testing; Fatigue Testing; Test rig; Pneumatic; FEA; Weld; Steel; Fillet Weld; S-N curve;

    Abstract : The use of recommended S-N curves, presented in current literature, to analyse and determine the fatigue life of a part is common practice in, inter alia, the construction industry.However, the recommended S-N curves are generally created for larger components used in mainly the construction industry.
