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. 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

   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

5. 4. 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
