  1. 16. Adhesive joining for crashworthiness : material data and explicit FE-methods

    Författare :Thomas Carlberger; Högskolan i Skövde; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adhesive joining; Dynamic fracture; Cohesive zone; Interphase Element; Bimaterial joining; Hybrid joints; Materials science; Teknisk materialvetenskap; Teknik; Technology;

    Sammanfattning : Today, crash simulations replace crash testing in the product development phase in theautomotive industry. High quality simulations enable shorter product development time andhigher competitiveness. LÄS MER

  3. 17. Structural Health Monitoring of Bridges : Model-free damage detection method using Machine Learning

    Författare :Cláudia Neves; Raid Karoumi; John Leander; Ignacio Gonzalez; Eleni Chatzi; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Health Monitoring; Machine Learning; Damage detection; Model-free based method; Artificial Neural Networks; Gaussian Process; Cost optimization; Byggvetenskap; Civil and Architectural Engineering;

    Sammanfattning : This is probably the most appropriate time for the development of robust and reliable structural damage detection systems as aging civil engineering structures, such as bridges, are being used past their life expectancy and beyond their original design loads. Often, when a significant damage to the structure is discovered, the deterioration has already progressed far and required repair is substantial. LÄS MER

  4. 18. Sequence- and structure guided engineering of proteins and enzymes for biotechnology and health applications

    Författare :Karen Schriever; Per-Olof Syrén; Elton P. Hudson; Eric A. Gaucher; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; protein engineering; enzymology; ancestral sequence reconstruction; antigen engineering; structural biology; terpene cyclases; enzyme thermodynamics; biocatalysis; phosphatases; allosteric regulation; Biotechnology; Bioteknologi;

    Sammanfattning : Proteins are highly diverse and sophisticated biomolecules that represent a cornerstone of biological structure and function and have been exploited in man-made applications for thousands of years. Those proteins that facilitate chemical reactions at physiologically relevant time-scales are referred to as enzymes. LÄS MER

  5. 19. Sustainability-, Buildability- and Performance-driven Structural Design

    Författare :Alexandre Mathern; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; NATURVETENSKAP; NATURAL SCIENCES; sustainability; structural engineering; civil engineering; design method; finite element analysis; concrete structures; material developments; buildability; performance; structural developments; requirements; construction technology; integrated design; bridges; constructability;

    Sammanfattning : The construction, maintenance and operation of infrastructure networks represent substantial impacts, both positive and negative, in all three dimensions of sustainability: economic, social and environmental. The greatest possibility to reduce the negative impacts and increase the positive ones is at the early design stage of construction projects. LÄS MER

  7. 20. Structural assessment procedures for existing concrete bridges : Experiences from failure tests of the Kiruna Bridge

    Författare :Niklas Bagge; Björn Täljsten; Paulo Cruz; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anchorage; carbon fibre reinforced polymers; concrete; existing bridges; finite element analysis; flexure; full-scale test; load-carrying capacity; residual prestress force; punching; safety verification; shear; structural assessment; structural behaviour; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : Assessing existing bridges is an important task in the sustainable management ofinfrastructure. In practice, structural bridge assessments are usually conducted usingtraditional and standardised methods, despite knowledge that these methods oftenprovide conservative estimates. LÄS MER
