  1. 11. Hydro-mechanical forming of aluminium tubes : on constitutive modelling and process design

    Författare :Mikael Jansson; Larsgunnar Nilsson; Odd Sture Hopperstad; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydroforming; Aluminium Extrusions; Anisotropic material; Solid mechanics; Fastkroppsmekanik;

    Sammanfattning : Tube hydroforming is a forming method which has several advantages. By using pressure in combination with material feeding it is possible to manufacture products with high structural integration and tight dimensional tolerances. The forming method is especially suited for aluminium alloys which have a relatively low ductility. LÄS MER

  4. 13. Constitutive models based on dislocation density : formulation and implementation into finite element codes

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

    Sammanfattning : Correct description of the material behaviour is an extra challenge in simulation of the materials processing and manufacturing processes such as metal forming. Material models must account for varying strain, strain rate and temperature, and changing microstructure. LÄS MER
