  2. 1. Wood and fibre mechanics related to the thermomechanical pulping process

    Author : Jan-Erik Berg; Per Engstrand; Per A. Gradin; Tomas Björkqvist; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acoustic emission; Chips; Compression tests; Defibration; Disc refiners; Energy consumption; Fibre structure; Force sensors; Fracture; Impact strength; Mathematical analysis; Moisture content; Picea abies; Refining; Stiffness degradation; Strains; Temperature; Thermomechanical pulping; Velocity; Chemical engineering; Kemiteknik;

    Abstract : The main objective of this thesis was to improve the understanding of some aspects on wood and fibre mechanics related to conditions in the thermomechanical pulping process. Another objective was to measure the power distribution between the rotating plates in a refiner. READ MORE

  4. 2. On the modeling of large ratcheting strains and anisotropy in pearlitic steel

    Author : Göran Johansson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Large strains; Plasticity; Anisotropy; Ratcheting; Kinematic hardening;

    Abstract : Thermodynamically consistent constitutive material models for describing the large strain response of polycrystalline metals are proposed. Emphasis is put on the multiaxial ratcheting under cyclic loading and the evolution of anisotropy in pearlitic steel. READ MORE

  5. 3. Endemic and epidemic Streptococcus pyogenes strains : reservoirs in recurrent pharyngotonsillitis reservoirs in recurrent pharyngotonsillitis reservoirs in recurrent pharyngotonsillitis
