  1. 6. Deformation and Fracture Behavior of Transparent Wood-Polymer Biocomposites

    Författare :Erik Jungstedt; Lars Berglund; Sören Östlund; Bent Sørensen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biocomposites; fracture mechanics; strain field measurement; cohesive zone modeling; mechanical properties; Solid Mechanics; Hållfasthetslära;

    Sammanfattning : Transparent wood-polymer biocomposites (TWPBs) are interesting wood-based materials with a unique combination of optical transmittance and mechanical properties. The wood substrate is delignified (removal of lignin) while the wood microstructure is preserved. LÄS MER

  3. 7. Finger-Joints for Laminated Beams : Experimental and Numerical Studies of Mechanical Behaviour

    Författare :Erik Serrano; Byggnadsmekanik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Finger-joints; Laminated timber; Testing; Nonlinear fracture mechanics; Finite Elemente Method; Lamininating effect;

    Sammanfattning : The introduction of laminated timber, glulam being an example, allowed many of the disadvantages associated with solid wood to be overcome. The disadvantages in question are mainly those related to the size and shape limits of structural elements made of solid wood and to the large variability in such material properties of solid wood as strength and stiffness.

  7. 10. Deformation Behaviour of A356-T7 Cast Aluminium Alloys Used in High Specific Power IC Engine Cylinder Heads

    Författare :Elanghovan Natesan; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aluminium alloys; fatigue; constitutive models; thermo-mechanical fatigue; a356; cylinder head;

    Sammanfattning : The constant development drive towards higher specific power and lower displacement engines in recent years to produce environmentally friendly high-performance cars has placed increasingly high thermal loads on the internal combustion engine materials. Further, the advent of hybrid power trains placing higher demands on quick starts and a rapid approach to maximum power necessitates the automotive industry to move towards a more robust computational thermo-mechanical fatigue life prediction methodology to develop reliable engines and reduce developmental costs.
