    Sammanfattning : About 70% of the plant species in the temperate zone are characterised by clonal growth, clonal species are also in majority in the Arctic and Subarctic where they affect the structure and composition of the vegetation. It is therefore of great importance to increase our knowledge about clonal plants and their growth and life histories. LÄS MER

  3. 2. Interfibre Joint Strength under Mixed Modes of Loading

    Författare :Mikael S. Magnusson; Sören Östlund; Kaarlo Niskanen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Interfibre joint strength; fibre-fibre cross; paper mechanics; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : The load carrying capacity of interbre joints are one of the key entities for build-up of strength inpaper materials. In order to gain insight in how to tailor the macroscopic properties of such materialsby chemical and/or mechanical treatments at a microscopic level, direct measurement of individualbre{bre crosses are typically performed.
