  2. 2. Dynamic Rating with Applications to Renewable Energy

    Author : Kateryna Morozovska; Patrik Hilber; Tor Laneryd; Hans Ezz Edin; Adamantios Marinakis; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; dynamic rating; dynamic line rating; dynamic transformer rating; power transformers; power system optimization; wind farm planning; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Dynamic rating (DR) of power components is a method for assessing real-time capacity of large scale power transmission and distribution devices (commonly: transmission lines, power transformers, underground cables) and using this knowledge for adjusting loading limits of these components. Dynamic rating of power lines or dynamic line rating (DLR) is a pioneering technology in the area of dynamic rating.

    Author : Joakim Lundqvist; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Abstract : The tube hydroforming process is still to be considered a new and advanced technique. The process has been adopted into several industries, e.g. automotive and aero. READ MORE

  4. 4. Concrete Structures Subjected to Blast Loading

    Author : Jonas Ekström; Chalmers University of Technology; []
    Keywords : dynamic response; numerical modelling; spalling; blast load; stain-softening; wave propagation; concrete; transverse reverse loading; cyclic crack propagation;

    Abstract : The interest for building safety with regards to highly dynamic events such as close by explosion has accelerated after the recent decades of terrorist attacks. The interest has expanded from civil defence shelters and pure military targets to also include civil buildings used for different civil functions. READ MORE

  5. 5. Dynamic neck formation in elastic-plastic tensile bars

    Author : Kristina Nilsson; Mekanik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dynamic loading; necking; inertia; localization zones; numerical simulation; finite elements; non-linear;

    Abstract : The time development of neck formation in ductile elastic-plastic bars is analyzed numerically in order to obtain a qualitative description of the features of dynamic neck localization under impact conditions. The full time history is visualized using contour plots of the time development of a strain rate parameter. READ MORE
