2. 1. Pulp displacement washing - An investigation of the influence of fibre and bed properties using a novel measurment technique

   Author : Jenny Lindau; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; displacement washing; pulp properties.; measurement technique; compression; dispersion; fibre damage; local properties; kraft pulp;

   Abstract : There are many incentives for making the pulp washing process as efficient as possible: an efficient separation of the pulp from the black liquor will increase energy efficiency, reduce costs by minimizing the need for make-up chemicals and improve the bleaching process. Research in this area has, however, been more or less neglected and in the existing literature there are many discrepancies as to how different parameters influence the washing process. READ MORE

4. 2. Investigations on moisture damage-related behaviour of bituminous materials

   Author : Umaru Bagampadde; Ulf Isacsson; Manfred Partl; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Moisture damage; State-of-the-Art; Stripping; Moisture sensitivity; Bituminous materials; Construction engineering; Konstruktionsteknik;

   Abstract : This doctoral thesis presents results of literature review on classical and contemporary aspects of stripping, as well as experimental investigations on moisture damage as influenced by bituminous materials. Previous research in the area of moisture damage was reviewed and synthesized into a state-of-the-art. READ MORE

5. 3. Continuum modelling of the mechanical response of paper-based materials

   Author : Eric Borgqvist; Hållfasthetslära; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; paperboard; constitutive modeling; anistropy; finte deformations; plasticity; damage; continuum mechanics;

   Abstract : Continuum based elasto-plastic-damage models for paperboard have been established in this work. The thesis begins with an introductory section that describes the mechanical properties of paperboard and some of the converting processes during forming of a package. READ MORE

6. 4. Adhesive Joints in Timber Engineering. Modelling and Testing of Fracture Properties

   Author : Erik Serrano; Byggnadsmekanik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wood; test method; tensile strength; stress distribution; size effect; numerical simulation; laminating effect; laminated beams; joint; glued-laminated timber; glued-in rod; fracture mechanics; finite element method; finger-joint; experiment; damage; constitutive modelling; adhesive; bending strength; Environmental technology; pollution control; Miljöteknik; kontroll av utsläpp; Construction technology; Anläggningsteknik; Material technology; Materiallära; materialteknik;

   Abstract : This thesis, which is a compilation of seven papers, concerns the mechanical testing, numerical analysis and constitutive modelling of wood-adhesive bonds in timber engineering. Applications such as finger-joints, glued-laminated timber and glued-in rods are considered. READ MORE

7. 5. Modelling Damage Evolution and Fracture of Paper Materials

   Author : Rickard Hägglund; Hållfasthetslära; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Paper material; Fracture mechanics; Tensile strength; Fibre network; Continuum damage mechanics; Non-local theory;

   Abstract : This thesis contains six papers dealing with different aspects of damage and fracture in paper. The work addresses the problem of material length scales in the context of deformation and fracture of paper materials. READ MORE
