  1. 21. Ductile Failure in High Strength Steel Sheets

    Författare :Oscar Björklund; Larsgunnar Nilsson; Odd-Geir Lademo; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Developments in computer-aided engineering and the rapid growth of computational power have made simulation-driven process and product development efficient and useful since it enables detailed evaluation of product designs and their manufacturing processes. In the context of a sheet metal component, it is vital to predict possible failure both during its forming process and its subsequent usage. LÄS MER

  3. 22. Mechanical properties of stainless steel clinched joints

    Författare :Per Sjöström; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Clinching is a joining method for sheet material where the joint is created without need of heat or additional material. The material is joined by local plastic deformation creating a geometrical locking. Since the materi al is not heated during joining, problems caused by HAZ or phase transformation during heating or cooling can be avoided. LÄS MER

  4. 23. Warm Sheet Metal Forming with Localized In-Tool Induction Heating

    Författare :Linus Larsson; Industriell Produktion; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; warm sheet metal forming. elevated temperature; aluminium; malgnesiurn. induction heating;

    Sammanfattning : The increasing use of light metals and high strength steel in the automobile industry, demands for new sheet metal forming processes that can be applied successfully. In this thesis the subject of warm sheet metal forming is studied. LÄS MER

  5. 24. Sheet metal trimming dies – characterisation methods of geometry and surface topography and the influence on wear

    Författare :Per Jonsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; finish milling; wear measurement; functional surface; trimming dies; scale-sensitive fractal analysis; surface roughness; polishing; surface characterisation; high strength steel; tool wear;

    Sammanfattning : In recent years, the life cycle of car models has decreased from 7 to 5 years and the volume sizes are becoming shorter in the automotive industry. The increasing number of car models introduced to the market means that a fewer number of parts must pay the costs for the tool/die design and manufacturing. LÄS MER

  7. 25. On Material Modelling of High Strength Steel Sheets

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

    Sammanfattning : 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.
