  2. 21. Modelling of Failure in High Strength Steel Sheets

    Author : Oscar Björklund; Larsgunnar Nilsson; Odd Geir Lademo; Linköpings universitet; []
    Keywords : ;

    Abstract : In this theses the high strength steel Docol 600DP and the ultra high strength steel Docol 1200M are studied. Constitutive laws and failure models are calibrated and veried by the use of experiments and numerical simulations. READ MORE

  4. 22. On Material Modelling of High Strength Steel Sheets

    Author : Rikard Larsson; Larsgunnar Nilsson; Odd-Sture Hopperstad; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; material modelling;

    Abstract : The work done in this thesis aims at developing and improving material models for use in industrial applications.The mechanical behaviour of three advanced high strength steel grades, Docol 600DP, Docol 1200M and HyTens 1000, has been experimentally investigated under various types of deformation, and material models of their behaviour have been developed.

  7. 25. Dissimilar joining of aluminium to ultra-high strength steels by friction stir welding

    Author : Wallop Ratanathavorn; Arne Melander; Gunnar Bolmsjö; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aluminium alloy; high strength steel; intermetallic; friction stir welding; dissimilar joining; SRA - Produktion; SRA - Production;

    Abstract : Multi-material structures are increasingly used in vehicle bodies to reduce weight of cars. The use of these lightweight structures is driven by requirements to improve fuel economy and reduce CO2 emissions. The automotive industry has replaced conventional steel components by lighter metals such as aluminium alloy. READ MORE
