  1. 16. Nonlinear modeling of reinforced dowel joints in timber structures : a combined experimental-numerical study

    Författare :Michael Schweigler; Josef Eberhardsteiner; Thomas K. Bader; Thierry Descamps; Vienna University of Technology; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Technology byts ev till Engineering ; Teknik; Byggteknik; Civil engineering; Forestry and Wood Technology; Skog och träteknik;

    Sammanfattning : Steel dowels are indispensable elements for the design of joints in modern timber structures. Dowels are broadly used because of their flexibility in design and easy assembling on-site, as well as due to their advantageous mechanical behavior. LÄS MER

  3. 17. Damage tolerance and residual strength of composite sandwich structures

    Författare :Peter H. Bull; KTH; []
    Nyckelord :sandwich structure; damage tolerance; carbon fiber; compression after impact;

    Sammanfattning : The exploitation of sandwich structures as a means toachieve high specific strength and stiffness is relatively new.Therefore, the knowledge of its damage tolerance is limitedcompared to other structural concepts such as truss bars andmonocoque plate solutions. Several aspects of the damage tolerance of sandwichstructures are investigated. LÄS MER

  4. 18. Continuous Fibre Reinforced Oxide/Oxide Composites

    Författare :Magnus Holmquist; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polycrystalline oxide fibre; zirconia; single crystal oxide fibre; hot isostatic pressing; hot pressing; alumina; mullite; sapphire; tape casting; interface; VibroIntrusion; interphase; continuous fibre reinforced ceramic composite; mechanical properties; oxide fibre; ceramic matrix composite;

    Sammanfattning : The appealing properties of ceramics include retention of strength and hardness at high temperatures, chemical inertness and low density. However, monolithic ceramics fail in a brittle, unpredictable manner making them unsuitable for many applications where reliability is a key requirement. LÄS MER

  5. 19. Synthesis and Characterization of Composite Materials for Thermoelectric Power Generation

    Författare :Richard Heijl; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : In a thermoelectric material, a temperature difference will give rise to an electric potential that is proportional to the temperature gradient. In a closed circuit, this potential can keep a current flowing as long as the temperature gradient is maintained. LÄS MER

  7. 20. Under Construction: Making Meaning of Social Sustainability in Strategic Planning Practice

    Författare :Hannah Saldert; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Urban planning; urban sustainability; sustainable development; ambiguous concepts; discourse; situational analysis; Gothenburg;

    Sammanfattning : While social sustainability is attracting attention in both policy and academia, there are still challenges when turning social sustainability policy into practice. Instead of making cities more socially sustainable, the meaning of social sustainability tends to change, become simplified, or disappear when it is actualized in practice. LÄS MER
