    • ON EVALUATION OF THE THREE-DIMENSIONAL ISOGEOMETRIC BEAM ELEMENT 

      Autor: Dvořáková, Edita; Patzák, Bořek
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)
      The exact description of the arbitrarily curved geometries, including conic sections, is an undeniable advantage of isogeometric analysis (IGA) over standard finite element method (FEM). With B-spline/NURBS approximation ...

    • ON OPTIMUM DESIGN OF FRAME STRUCTURES 

      Autor: Tyburec, Marek; Zeman, Jan; Kružík, Martin; Henrion, Didier
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)
      Optimization of frame structures is formulated as a non-convex optimization problem, which is currently solved to local optimality. In this contribution, we investigate four optimization approaches: (i) general non-linear ...

    • ON TUNING THE DYNAMIC LOAD BALANCING FEM FRAMEWORK 

      Autor: Bošanský, Michal; Patzák, Bořek
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)
      Developments in computer hardware are currently bringing new opportunities for numerical modelling. The current trend in technology is parallel processing making use of multiple processing units simultaneously to solve a ...

    • PRE-PROCESSING OF ADDITIVE MANUFACTURING INPUT FILES FOR NUMERICAL SIMULATION 

      Autor: Voříšek, Jan; Patzák, Bořek
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)
      In this contribution, we present the concept of a 3D printer software emulator facilitating the creation of a spatial finite element mesh suitable for the printing process simulation. The concept is based on gradual ...

    • RESPONSE AND DAMAGE EVOLUTION OF SINGLE EDGE NOTCHED TIMBER BEAMS UNDER THREE-POINT BENDING 

      Autor: Šmídová, Eliška; Kabele, Petr; Šejnoha, Michal
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)
      Two groups of small-size single edge notched beams (SENB) made of European spruce (Picea abies) were tested in three-point bending (3PB) until failure under displacement control. The first group comprised of eight solid ...

    • SIZE EFFECT ON THE ULTIMATE DRYING SHRINKAGE OF CONCRETE - EXPERIMENTAL EVIDENCE AND ENGINEERING PRACTICE 

      Autor: Dohnalová, Lenka; Havlásek, Petr
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)
      The design and behavior of creep-sensitive structures can be to a large extent dependent on the evolution of drying shrinkage. Drying shrinkage of concrete measured on standard laboratory specimens is very time demanding, ...

    • THE INFLUENCE OF THE USE OF RECYCLED GYPSUM ON THE PROPERTIES OF GYPSUM PRODUCTS IN LABOR CONDITIONS 

      Autor: Sekavová, Hana; Herrmann, Jakub; Prošek, Zdeněk; Nyč, Miroslav; Karra’a, George
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)
      The article presents the first results from research, which is deal with recycling of plaster boards and use of the resulting material. The research is carried out within the project MPO Trio c. FV30359 “Recyklace ...

    • THECOMPARISON OF TWO DIFFERENT SPORTING EVENTS BASEDONTHETYPICALBEHAVIOROFTHEACTIVE SPECTATORS AND GRANDSTAND VIBRATIONS INDUCED BY THEM 

      Autor: Verner, Martin
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)
      The paper describes especially the typical behavior of two active spectators crowds involved in two substantially different sporting events, namely, ice hockey games and a biathlon world cup competition. In both cases, ...
