  1. 21. Hybrid Joining of Aluminum to Thermoplastics with Friction Stir Welding

    University essay from KTH/Materialvetenskap

    Author : Wallop Ratanathavorn; [2012]
    Keywords : friction stir welding; hybrid welding;

    Abstract : Hybrid structures including aluminum-thermoplastic and aluminum-reinforced thermoplastic composite are increasingly important in the near future innovations due to its lightweight and high strength-to-weight ratio. A critical point for metal-polymer application is that sound joining of these materials is difficult to achieve owing to a large difference in surface energy and dissimilar structure between metal and polymer.

  3. 22. Static and fatigue design of load carrying welded joints in high strength steels : -In collaboration with Cargotec Sweden AB

    University essay from KTH/Lättkonstruktioner

    Author : Noman Ali Mumtaz; Mansoor Khurshid; [2011]
    Keywords : Strength mismatch; penetration ratio; full penetration; partial penetration; Eurocode 3; AWS D1.1; BSK 07; HAZ; ultimate strength capacity; FE analysis; effective notch concept; beam theory analysis; sub modelling.;

    Abstract : This thesis work is carried out in Cargotec Sweden AB, Bromma Conquip to study the behavior of load carrying welded joints in different weld metal strength mismatch conditions and various penetration ratios. Static and fatigue strength calculations have been made using FEA and experimentation. READ MORE

  4. 23. Quality Inspection and Fatigue Assessment of Welded Structures

    University essay from KTH/Lättkonstruktioner

    Author : Eric Lindgren; Thomas Stenberg; [2011]
    Keywords : ;

    Abstract : Recently, Volvo Construction Equipment AB has developed a weld class system forimperfections in welded joints, which contains demands for the toe radii, cold laps, undercutsetc. and where root defects are treated as requirements on the drawing. READ MORE

  5. 24. Crack Propagation in Cruciform Welded Joints : Study of Modern Analysis

    University essay from Institutionen för teknikvetenskaper

    Author : Kristin Nielsen; [2011]
    Keywords : crack propagation; fatigue assessment; effective notch; fracture mechanics;

    Abstract : This thesis is investigating how the effective notch method can be used for fatigue assessment of welded joints.  The effective notch method is based on a finite element analysis where the joint is modeled with all notches fictitiously rounded with a radius of 1 mm. READ MORE

  6. 25. Optimization of Weld Nut Geometry by Simulation

    University essay from KTH/Industriell produktion

    Author : Mattias J Lindén; [2010]
    Keywords : ;

    Abstract : This project covers resistance projectionwelding of HP weld nuts and simulationsof these weld nuts welded to Dogal(350YP, 600DP, 800DP) and HyTens1000. When the simulation results werecompared to results in the previous report,Resistance Nut Welding of High StrengthSteel, it showed that the simulations ofHPM8 weld nuts were more accurate thenthe HPM6 simulations.
