    • 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 ...

    • RELATION BETWEEN HARDNESS OF (Ti, Al)N BASED MULTILAYERED COATINGS AND PERIODS OF THEIR STACKING 

      Autor: Zaoui, Mehdi; Bourceret, Alexandre; Gaillard, Yves; Giljean, Sylvain; Rousselot, Christophe; Pac, Marie-José; Richard, Fabrice
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)
      This study aims to model, by using a finite element method, the relationship between the hardness and the period Λ of metal/nitride multilayer coatings (Ti0.54Al0.46/Ti0.54Al0.46N)n in order to understand the increase of ...

    • 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 ...

    • ROLE OF FLUID ON THE CONTACT DEFORMATION RESPONSE OF BIOLOGICAL TISSUE 

      Autor: Swain, Michael V.
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)
      This paper will focus on the role of fluids on the indentation deformation response of tooth and eye tissues. All natural biological materials contain fluid and function in a fluidic environment, which plays a critical ...

    • 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, ...

    • THERMAL ANALYSIS OF DRY STORAGE AND TRANSPORTATION CASKS CASTOR USING COBRA-SFS 

      Autor: Ševeček, Martin; Valach, Mojmír; Lee, Chih-Hao
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)
      State Office for Nuclear Safety is a regulator body in the Czech Republic handling also licensing of storage and transportation casks (SCs) of the spent nuclear fuel (SNF). One of the main concerns for the dry storage of ...

    • WHY MONITOR ACOUSTIC EMISSIONS DURING NANOMECHANICAL TESTS? 

      Autor: Čtvrtlík, Radim; Václavek, Lukáš; Tomáštík, Jan
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)
      Acoustic Emissions (AE) monitoring has been proved as an effective non-destructive technique at the macro scale. Nevertheless, it may also be employed at nano/micro scale during nanomechanical and nanotribological testing. ...
