  1. 1. Wood fibre deformation in combined shear and compression

    Författare :Federica De Magistris; Anders Eriksson; Ola Dahlblom; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Arcan; compression; density; energy; finite element analysis; Iosipescu; Picea abies; shear; wood; Cellulose and paper engineering; Cellulosa- och pappersteknik;

    Sammanfattning : Mechanical pulping for producing pulps from softwood suitable for printing grade papers, like news, is a highly energy-intensive process consuming around 2000 kWh/t in electrical energy. Due to increasing energy costs and environmental issues there is a high demand for decreasing this energy consumption. LÄS MER

  3. 2. The modified Iosipescu shear test for orthotropic materials

    Författare :Niklas Melin; Jonas Neumeister; Gradin Per; KTH; []
    Nyckelord :composite; modified Iosipescu tet; shear test; strain field uniformity; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : AbstractThe Iosipescu shear test, also known as asymmetric four point bending of a V-notched beam,is frequently used for measuring in-plane shear properties of composites. The ASTM standard(ASTM D-5379-05) regulates how the test is to be performed. LÄS MER

  7. 5. Behaviour and material properties of composites for crash modelling

    Författare :Thomas Bru; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; carbon fibre composite; non-crimp fabric; crushing; mechanical testing.;

    Sammanfattning : The transport industry must find solutions to reduce its impact on climate change. A promising way to reduce the weight of vehicles and therefore to reduce the CO2 emissions is to introduce components made of lightweight composite materials, in particular laminated carbon fibre reinforced polymers (CFRPs).
