  2. 1. Thermal stresses in load-bearing glass-timber components

    Author : Karin Lundstedt; Erik Serrano; Ola Dahlblom; Linnéuniversitetet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Thermal stresses; thermal failure; glass and wood construction; incident solar radiation; shading; cracks; temperature difference; finite element method.; Technology byts ev till Engineering ; Teknik;

    Abstract : Thermal stresses can arise in glass used in architectonic realisations in buildings as a result of solar irradiation:  that is, sunlight.  The magnitude of these thermal stresses depends on the temperature conditions in the glass in terms of the temperature differences between warm and cold areas.

  4. 2. Compressive Failure of NCF Composites

    Author : Anton Shipsha; Magnus Burman; Zuheir Barsoum; Leif Asp; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vehicle and Maritime Engineering; Farkostteknik;

    Abstract : The necessity to reduce environmental impact promotes transportation industry to reduce energy consumption of vehicles. One possible way to improve vehicles' structural efficiency is to utilize modern composite materials that offer excellent mechanical performance-to-weight ratio. READ MORE

  5. 3. Prognostics and Health Management of Engineering Systems for Operation and Maintenance Optimisation

    Author : Madhav Mishra; Matti Rantatalo; Kai Goebel; Kalevi Huhtala; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Prognostics and Health Management PHM ; Diagnostics; Prognostics; Bayesian; Hierarchical; L10; Prediction; Bearing; Li-ion battery; RUL; Particle filter; Model-based; Data-driven; Algorithms; Railway track geometry; Operation and Maintenance Engineering; Drift och underhållsteknik;

    Abstract : Prognostics and health management (PHM) is an engineering discipline that aims to maintain system behaviour and function and ensure mission success, safety and effectiveness. Prognostics is defined as the estimation of remaining useful life. READ MORE

  6. 4. Rotordynamic Modeling and Characterization of Support Elements in Vertical Machines

    Author : Gudeta Benti; Jan-Olov Aidanpää; Rolf Gustavsson; Ilmar Santos; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rotordynamic; Support Element; Bearing; Squeeze Film Damper; Hydropower; Vertical Machine; Machine Design; Maskinkonstruktion;

    Abstract : The dynamic properties of rotating machines are highly influenced by interconnecting devices, such as bearings, seals, or squeeze-film dampers. They play a significant role in regulating the characteristics of the interaction between the rotating and stationary parts of the machines. READ MORE

  7. 5. Soil-Steel Composite Bridges : Research advances and application

    Author : Amer Wadi; Raid Karoumi; Lars Pettersson; Ian D. Moore; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flexible culvert; Soil‒steel composite bridge; Sloping terrain; Swedish design method; Finite element model; Ultimate capacity; Avalanche load; Failure load; Low soil cover; Failure mechanism; Long-span; Byggvetenskap; Civil and Architectural Engineering;

    Abstract : Soil-steel composite bridges are considered competitive structures being an economical alternative to similar span concrete bridges. This frequently stimulates practitioners to push their design limits and expand the different areas of application including their performance in sloping terrain. READ MORE
