  2. 6. Towards Product Structure Management in Heterogeneous Environments

    Author : Daniel Svensson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PDM; Product structure management; product data management; product development;

    Abstract : The use of computer support in product development and manufacturing has introduced new possibilities and new requirements for information management. The parts, systems, functions and other elements used to represent the structure of a product form what is called a product structure, which is managed by support from information systems. READ MORE

  4. 7. Performance model for unbound grnular materials pavements

    Author : Tatek Fekadu Yideti; Björn Birgisson; Andrew Dawson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; unbound granular materials; aggregate; packing theory; gradation; primary structure; secundary structure; permanent deformation; resilient modulus;

    Abstract : Recently, there has been growing interest on the behaviour of unbound granular material in road base layers. Researchers have studied that the design of a new pavement and prediction of service life need proper characterization of unbound granular materials, which is one of the requirements for a new mechanistic design method in flexible pavement.

  7. 10. Stainless Steel Corrugated Web Girders for Composite Road Bridges: Concept Evaluation and Flange Buckling Resistance

    Author : Fatima Hlal; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Investment cost; Genetic algorithm; Duplex stainless steel; LCC; Corrugated web; Flange buckling resistance; Optimization; Composite bridges; LCA; Road bridges;

    Abstract : Achieving a sustainable bridge design requires careful consideration of economic viability and environmental impact over the entire lifespan of the structure. While stainless steel is recognized for its excellent life cycle performance, its high cost prevents it from being used to a larger extent in bridges. READ MORE
