    Författare :Johan Magnusson; Anders Ansell; Mikael Hallgren; Richard Malm; Jaap Weerheijm; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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; Civil and Architectural Engineering; Byggvetenskap;

    Sammanfattning : 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. LÄS MER

  4. 3. Shear Behaviour of Adhesive Layers

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

    Sammanfattning : 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. LÄS MER

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

    Författare :Marie Byenfeldt; Anders Elvin; Per Fransson; Odd Helge Gilja; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 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;

    Sammanfattning : 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. LÄS MER
