  1. 16. Characterisation methods and simulation of deformation and failure in metal forming processes

    Författare :Göran Lindkvist; Larsgunnar Nilsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : Tools for numerical analysis is a prerequisite in product development. Variations of the finite element method is widely used for simulation of metal manufacturing processes, for example sheet metal forming and hot stamping. LÄS MER

  3. 17. 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

  4. 18. A Study on Microstructure-Dependent Deformation and Failure Properties of Boron Alloyed Steel

    Författare :Stefan Golling; Larsgunnar Nilsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : Developments in the automotive industry are driven by customer desires and legislative authorities. Legislation has restricted the emissions standards for vehicles, and has mandated the need for higher safety standards. LÄS MER

  5. 19. A study on wear characteristics of high strength steels under sliding contact

    Författare :Abdulbaset Mussa; Pavel Krakhmalev; Jens Bergström; Jens Hardell; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; High strength steels; thread joint wear; punch wear; sliding wear; surface cracking; reciprocal sliding; fatigue; surface delamination; white etching layer; nano-structured layer; friction; Materialteknik; Materials Engineering;

    Sammanfattning : In the last decades, significant improvements regarding the design, materials and technology of rock drills have been made. Likewise, in sheet metal forming, forming tools experience very high contact pressures when processing high strength steel sheets. LÄS MER

  7. 20. Predicting Sheared Edge Characteristics of High Strength Steels

    Författare :Olle Sandin; Daniel Casellas; Pär Jonsén; Jörgen Kajberg; Rickard Östlund; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : An efficient way of reducing CO2 emissions from the transportation sector is to reduce the vehicle weights, i.e. lightweighting. A common strategy for lightweighting of vehicles is to replace the steels used to build structural parts of the vehicle, usually manufactured by metallic sheets, with stronger, advanced high strength steel (AHSS) grades.
