    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

  2. 2. Rheumatoid Arthritis in a 10-Year Perspective, Outcome for Patients Followed from Early Disease

    Author : Elisabet Lindqvist; Reumatologi och molekylär skelettbiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; reumatologi; muskelsystem; rheumatology locomotion; Skelett; COMP; Skeleton; muscle system; Anti-IL-1alpha; Anti-CCP; Rheumatoid factor isotypes; Mortality; Radiographic progression; Joint damage; Disease activity; HAQ; SOFI; Disability; Prognosis; Rheumatoid arthritis; Outcome;

    Abstract : Rheumatoid arthritis (RA) is characterized by persistent inflammation, progressive joint damage and disability. This thesis describes the outcome after 10 years in a cohort of 183 RA patients (116 women, 67 men) recruited 1985-89. The mean age was 51 years and symptom duration 11 months at inclusion.

  3. 3. Interfibre Joint Strength under Mixed Modes of Loading

    Author : Mikael S. Magnusson; Sören Östlund; Kaarlo Niskanen; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Interfibre joint strength; fibre-fibre cross; paper mechanics; Solid Mechanics; Hållfasthetslära;

    Abstract : The load carrying capacity of interbre joints are one of the key entities for build-up of strength inpaper materials. In order to gain insight in how to tailor the macroscopic properties of such materialsby chemical and/or mechanical treatments at a microscopic level, direct measurement of individualbre{bre crosses are typically performed.

  4. 4. Computational Models of Adhesively Bonded Joints

    Author : Peter Schmidt; Anders Klarbring; Ulf Stigh; Linköpings universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; adhesively bonded joint; asymptotic expansion; finite element; damage mechanics; Engineering mechanics; Teknisk mekanik;

    Abstract : Simulations using the Finite Element Method (FEM) play an increasingly important role in the design process of joints and fasteners in the aerospace industry. In order to utilize the potential of such adhesive bonding, there is an increasing need for effective and accurate computational methods. READ MORE

  5. 5. Analysis of rail breaks and insulated joint deterioration

    Author : Johan Sandström; Chalmers University of Technology; []
    Keywords : Rail breaks; Heavy Haul; Insulated joints; Wheel flats; Railway mechanics; Material fatigue;

    Abstract : The thesis deals with fatigue related issues in the field of railway mechanics. In particular rail breaks and deterioration of insulating joints are investigated. The study is largely motivated by plans to increase allowed axle loads in Sweden. READ MORE
