  3. 3. Micromechanical Modelling of Wood and Fibre Properties

    Författare :Kent Persson; Byggnadsmekanik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental technology; Byggnadsteknik; Building construction; Microfibril angle; Density; Hygroexpansion; Stiffness; Simulation; Wood; Fibre; pollution control; Miljöteknik; kontroll av utsläpp; Material technology; Materiallära; materialteknik;

    Sammanfattning : Wood is a material with mechanical properties that vary markedly, both within a tree and among trees. Moisture changes lead to shrinkage or swelling and modify the mechanical properties. LÄS MER

  4. 4. Hygroelastic behaviour of wood-fibre based materials on the composite, fibre and ultrastructural level

    Författare :Razvan Cristian Neagu; Kristofer Gamstedt; Staffan Toll; KTH; []
    Nyckelord :wood fibres; ultrastructure; structure-property relations; microfibril angle; composites; characterization methods; hygroelastic properties; micromechanics; modelling; reinforcement potential; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Wood fibres can be used as reinforcement in plastics for load carrying purposes. Some advantages compared with conventional man-made fibres are that wood fibres come from a renewable resource, have high specific stiffness and strength, are generally less hazardous to health, biodegradable, and can be manufactured at low cost and high volumes.

  5. 5. Grain Size and Solid Solution Strengthening in Metals

    Författare :Dilip Chandrasekaran; KTH; []
    Nyckelord :strengthening mechanisms; flow stress; solid solution strengthening; grain size strengthening; micromechanical modelling; AFM; EBSD;

    Sammanfattning : The understanding of the strengthening mechanisms is crucialboth in the development of new materials with improvedmechanical properties and in the development of better materialmodels in the simulation of industrial processes. The aim ofthis work has been to study different strengthening mechanismsfrom a fundamental point of view that enables the developmentof a general model for the flow stress. LÄS MER
