  2. 21. Compaction- and strength properties of stabilised and unstabilised fine-grained tills

    Author : Per Lindh; Byggnadsmekanik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Väg- och vattenbyggnadsteknik; Compaction; Fine-grained tills; Strength; Civil engineering; Soil stabilisation modification; hydraulic engineering; soil mechanics; offshore technology; Material technology; Materiallära; materialteknik;

    Abstract : Fine-grained soils are often regarded as problematic soils in earthworks because of their water- and frost sensitivity. Only limited amounts of fine-grained tills are used as earthwork material today. READ MORE

  4. 22. 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

  5. 23. Network Modelling for Evaluation of Mechanical Properties of Cellulose Fibre Fluff

    Author : Susanne Heyden; Byggnadsmekanik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydraulic engineering; Civil engineering; fracture; fibres; computer simulation; offshore technology; soil mechanics; Väg- och vattenbyggnadsteknik;

    Abstract : A network mechanics model for cellulose fibre fluff is proposed. 2D and 3D versions of the model have been implemented and the influence of various micro-level parameters on the global mechanical performance has been determined by means of computer simulations. READ MORE

  6. 24. Modeling of material behavior in metal forming

    Author : Håkan Hallberg; Hållfasthetslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : With an increasing demand to improve efficiency and to cut costs, the industry is constantly seeking to reduce the time and money spent in product development and manufacturing. Use of computer-based simulations has become more or less a standard tool to meet this demand. READ MORE

  7. 25. 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
