  2. 2. Shear in Concrete Structural Elements Subjected to Dynamic Loads

    Author : Johan Magnusson; Anders Ansell; Mikael Hallgren; Richard Malm; Jaap Weerheijm; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Dynamic load; initial response; shear failure; shear capacity; numerical simulations; bond; shear span; support reactions; Dynamisk last; initial respons; skjuvbrott; skjuvkapacitet; numeriska simuleringar; förankring; skjuvspännvidd; upplagsreaktioner; Byggvetenskap; Civil and Architectural Engineering;

    Abstract : Concrete structural elements subjected to severe dynamic loads such as explosions at close range may cause shear failures. In the Oklahoma City bombing in 1995 two concrete columns on the ground level were reported to have failed in shear. READ MORE

  3. 3. Shear Behaviour of Adhesive Layers

    Author : Karin Leffler; Högskolan i Skövde; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Adhersive layer; shear; ENF-specimen; stress-deformation relation; experimental method; J-integral; inverse method; Engineering mechanics; Teknisk mekanik; Teknik; Technology;

    Abstract : An experimental method to determine the complete stress versus deformation relation for a thin adhesive layer loaded in shear is presented. The work is based on a classical specimen geometry, i.e. the end-notch flexure specimen (ENF-specimen) and the experiments are evaluated based on an inverse method. READ MORE

  4. 4. Ultrasound based shear wave elastography of the liver : a non-invasive method for evaluation of liver disease

    Author : Marie Byenfeldt; Anders Elvin; Per Fransson; Odd Helge Gilja; Umeå universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anthropometric measurement; diagnostic imaging; elasticity imaging technique; blood supply; BMI; body position; fatty liver; liver disease; hepatic steatosis; liver fibrosis; liver stiffness; obesity; postural change; pressure; probe; sex characteristic; shear wave elastography; skin-to-liver capsule distance; transducer and ultrasonography; Radiography; radiografi;

    Abstract : Background: Detecting liver disease at an early stage is important, given that early intervention decreases the risk of developing cirrhosis and subsequently hepatocellular cancer (HCC). The non-invasive ultrasound-based shear wave elastography (SWE) has been used clinically for a decade to assess liver stiffness. READ MORE

  5. 5. FRP shear strengthening of reinforced concrete beams

    Author : Gabriel Sas; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fiber reinforced polymers; shear; reinforced concrete; strengthening; model; comparison; literature review; Structural Engineering; Konstruktionsteknik;

    Abstract : The shear failure mechanisms of flexural reinforced concrete (RC) members is highly complex; its precise details cannot be explained with simple analytical relationships, and are the topic of considerable scientific debate. The studies described and examined the three most used shear theories in the world – the fixed angle truss model (45°TM), the variable angle truss model (VAT), and modified compression field theory (MCFT).
