2. Micromechanical Modelling of Wood and Fibre Properties
Abstract : 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. READ MORE

3. On the Modelling of Mechanical Dewatering in Papermaking
Abstract : Most of the water fed into a paper machine is removedmechanically in the forming and press sections. One of thefactor which has an important influence on mechanicaldewatering, i.e. in both forming and pressing, is thestress-strain behaviour of the fibre network. READ MORE

5. Dimensional Stability of Paper : Influence of Fibre-Fibre Joints and Fibre Wall Oxidation
Abstract : Papper är ett mycket mångsidigt material. Trots detta finns det ett flertal egenskaper som begränsar papperets användbarhet. Ett av de större problemen med cellulosa- och lignocellulosafibrer är att de sänker sin fria energi genom att sorbera vatten, och denna sorption förändrar papperets dimensioner. READ MORE
