  1. 26. Efficient finite element modelling and simulation of welding

    Författare :Henrik Runnemalm; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design;

    Sammanfattning : This thesis presents development of methods, methodologies and tools for efficient finite element modelling and simulation of welding. A novel 8- to 16-noded solid shell element has been developed. It uses only displacement degrees of freedom, thus it can easily be connected with a regular brick element. LÄS MER

  3. 27. Modelling and simulation of welding and metal deposition

    Författare :Andreas Lundbäck; Jesper Hattel; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design; Material Mechanics; Materialmekanik;

    Sammanfattning : Fusion welding is one of the most used methods for joining metals. This method has largely been developed by experiments, i.e. trial and error. LÄS MER

  4. 28. Laser welding and cladding : the effects of defects on fatigue behaviour

    Författare :Md. Minhaj Alam; Stewart Williams; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Manufacturing Systems Engineering; Produktionsutveckling;

    Sammanfattning : The thesis focuses on weld defects in laser processed materials (for laser welding, laser hybrid arc welding and laser cladding) and their effect on the fatigue life of components. Component properties were studied with particular emphasis on the macro and micro surface geometry, weld defects and clad defects. LÄS MER

  5. 29. Investigation and modelling of friction stir welded copper canisters

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

    Sammanfattning : 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. LÄS MER

  7. 30. MODELLING AND SIMULATION OF ELASTIC & PLASTIC BEHAVIOUR OF PROPAGATING IMPACT WAVE : Impact- echo and Explosive welding process development

    Författare :Mohammad Tabatabaee Ghomi; Jafar Mahmoudi; Golamhoosin Liaghat; Hamid Bahai; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy- and Environmental Engineering; energi- och miljöteknik;

    Sammanfattning : A force that is applied dynamically in a short period of time is called an impact force (shock wave). Due to the concentrated application of force on a small area in a fraction of a second, unique applications have emerged that other types of loadings are not capable of performing. LÄS MER
