  3. 22. Improvement on cellulose accessibility and reactivity of different wood pulps

    Författare :Viviana Köpcke; Monica Ek; KTH; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; cellulose; accessibility; reactivity; enzymatic treatment; mechanical treatment; chemical treatment; dissolving pulp; paper grade pulps; Wood fibre and forest products; Träfiber- och virkeslära;

    Sammanfattning : Cellulosans tillgänglighet och reaktivitet är nyckelparametrar vid framställning av regenererad cellulosa och cellulosaderivat. Det är välkänt att på grund av cellulosans kristallina struktur är tillgängligheten begränsad för lösningsmedel och olika reagens. LÄS MER

  4. 23. Branch Identification in Elastic Stability Analysis

    Författare :Anders Magnusson; Hållfasthetslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vacuum technology; hydraulics; Mechanical engineering; Produktionsteknik; Production technology; FEM; computer simulation; bifurcation; stability; vibration and acoustic engineering; Maskinteknik; hydraulik; vakuumteknik; vibrationer; akustik;

    Sammanfattning : In this thesis, methods to determine the static postbuckling behaviour of elastic structures undergoing large deformations, are considered and developed. Since the governing non-linear equations usually becomes too complex to be handled analytically, the main focus has been on developing methods that can be incorporated into a numerical solution scheme, such as the finite element method.

  5. 24. Electron beam powder bed fusion processing of stainless steels

    Författare :Stefan Roos; Lars-Erik Rännar; Andrei Koptioug; Carlos Alberto Botero Vega; Iain Todd; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additive manufacturing; Electron beam powder bed fusion; PBF-EB; Stainless steel; Mechanical properties; Micro-structure; Nanoindentation;

    Sammanfattning : Additive manufacturing (AM) is still a relatively new technology. In contrast to traditional machining where material is removed from a blank, AM is used to fuse a feedstock material into complex shapes, layer by layer, starting from an empty workspace. LÄS MER
