1. 1. Mechanical Characterization of Engineering Materials by Modal Testing

   Författare :Daniel Larsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; material variability; modal testing; non-destructive test methods; damping ratios; timber beams; plastic panels; aluminium panel; elastic constants; concrete curing; wood-based panels; solids; high-strength concrete; anisotropic materials;

   Sammanfattning : This thesis deals with the use of modal testing for establishing elastic constants of engineering materials and for indicating material variability in terms of stiffness and damping properties. The methodology using modal testing techniques, is applied to timber beams, high strength concrete prisms, wood-based panels (oriented strand board and chipboard), an aluminium alloy panel and plastic laminate panels (high-pressure laminate).

3. 2. Stressed-Skin Panels of Mixed Construction - Using Wood-Based Materials, Especially Chipboard

   Författare :Robert Kliger; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stressed-skin panel behaviour; wood; timber; steel; joists;

   Sammanfattning : Stressed-skin panels are structural elements widely used as floors, roofs and so on. In such panels, flanges of sheet material interact with webs of beams (joists). LÄS MER

4. 3. Requirements for wood-based lightweight panels intended for furniture and interior use

   Författare :Jonaz Nilsson; Jimmy Johansson; Linnéuniversitetet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Forestry and Wood Technology; Skog och träteknik;

   Sammanfattning : Introduction: Throughout many parts of the world, forests exist in one form or another. And for the timber from these forests to be used, it must be processed by, for example, sawing into planks and dried. Studies have shown that profits for the forest owners increase from beneficial processing of these raw materials. LÄS MER

5. 4. Manufacture of straw MDF and fibreboards

   Författare :Sören Halvarsson; Håkan Edlund; Magnus Norgren; Thomas Amidon; Mittuniversitetet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rice; Wheat; Straw; MDF; HDF; UF; MUF; MDI; Non-resin; binderless MDF; Ash; Silicon; SEM; Hot-pressing; MOR; MOE; IB; Thickness swelling; MDF properties; fibre swelling; WRV; Refining; Defibration.; NATURAL SCIENCES; NATURVETENSKAP; Chemical engineering; Kemiteknik; Chemical process and manufacturing engineering; Kemisk process- och produktionsteknik;

   Sammanfattning : The purpose of this thesis was to develop an economical, sustainable, and environmentally friendly straw Medium Density Fibreboard (MDF) process, capable of full-scale manufacturing and to produce MDF of requested quality. The investigated straw was based on wheat (Triticum aestivum L.) and rice (Oryzae sativa L.). LÄS MER

7. 5. Parametric FE-modelling of non-linear racking behaviour of light-frame shear walls and modules used for multi-storey timber buildings

   Författare :Le Kuai; Sigurdur Ormarsson; Johan Vessby; Marie Johansson; Kay-Uwe Schober; Linnéuniversitetet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Byggteknik; Civil engineering;

   Sammanfattning : Wood is a sustainable material from nature that has a longstanding traditionas a building material. Compared to other construction materials, such as steeland concrete, the significance of using structural timber and engineered wood products has increased in recent years because they are regarded as a renewable source and require a low carbon footprint and less energy consumption during production.
