  2. 16. Fatigue Strength of Friction Stir Welded Joints in Aluminium

    Author : Mats Ericsson; Rolf Sandström; Ole Terje Midling; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Applied Materials Technology; friction stir welding; fatigue; mechanical properties; welding speed; softening; Materialvetenskap; Materials science; Teknisk materialvetenskap;

    Abstract : Solid state Friction stir welding (FSW) is of major interest in the welding of aluminium since it improves the joint properties. Many applications where Al-alloys are used are subject to varying load conditions, making fatigue failure a critical issue. READ MORE

  4. 17. Fatigue of Spot Welded Joints: Experiments and Life Predictions

    Author : Hans-Fredrik Henrysson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; crack closure; crack propagation; crack initiation; finite element method; damage accumulation; variable amplitude; fracture mechanics; fatigue; spot welds;

    Abstract : Methods to assess the fatigue strength of spot welds in built-up structures are used on a daily basis in the automotive industry. Efficient and reliable numerical methods make it possible to achieve designs with low weight, low manufacturing costs and good durability within short development cycles, since the number of prototypes built can be reduced.

  6. 19. Investigation and modelling of friction stir welded copper canisters

    Author : Therese Källgren; Rolf Sandström; Hannu Hänninen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Friction Stir Welding FSW ; Copper; Welding; Finite Element Method FEM ; SKB; Material flow; Materials science; Teknisk materialvetenskap;

    Abstract : This work has been focused on characterisation of FSW joints, and modelling of the process, both analytically and numerically. The Swedish model for final deposit of nuclear fuel waste is based on copper canisters as a corrosion barrier with an inner pressure holding insert of cast iron. READ MORE
