  1. 1. Resistance of cold-formed high strength steel sections : Effect of cold-formed angle

    Författare :Anh Tuan Tran; Lars Bernspång; Ove Lagerqvist; Torsten Höglund; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stålbyggnad; Steel Structures;

    Sammanfattning : Cold-formed steel members are increasingly used in industrial and civil construction. Their use allows optimised member cross sections and shapes, thereby reducing the amount of steel used as well as the weight of the structures and, consequently, reducing harmful effects on the environment.

  5. 4. Modeling of Cold Pilgering of Tubes

    Författare :Yağız Azizoğlu; Lars-Erik Lindrgren; Denis Sornin; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cold pilgering; finite element method; tube forming; tool elasticity; roll flattening; Material Mechanics; Materialmekanik; Steel Forming and Surface Engineering;

    Sammanfattning : Cold pilgering is a challenging tube forming process in terms of modeling due to the complexity in kinematic of tools, friction condition and material behavior. The process development has mostly been based on simple formulas and costly full-scale tryouts. LÄS MER

  7. 5. Modeling of Cold Pilgering of Stainless Steel Tubes

    Författare :Yağız Azizoğlu; Lars-Erik Lindgren; Jonas Edberg; Per Gradin; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cold pilgering; finite element method; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : Cold pilgering is a complex forming process used to produce seamless tubes in terms of modeling due to the complexity in kinematic of tools, friction condition and material behavior. The process development has mostly been based on simple formulas and costly full-scale tryouts. LÄS MER
