    • COMPRESSIVE PROPERTIES OF AUXETIC STRUCTURES WITH CONTROLLED STIFFNESS OF STRUT JOINTS 

      Author: Doktor, Tomáš; Fíla, Tomáš; Koudelka, Petr; Kytýř, Daniel; Jiroušek, Ondřej
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
      Presented paper deals with experimental study on compressive properties of auxetics with controlled stiffness of strut joints. The variable strut joints properties were simulated by adding extra amount of material in the ...

    • DIRECT MEASUREMENT OF REACTION FORCES DURING FAST DYNAMIC LOADING 

      Author: Falta, Jan; Adorna, Marcel; Fíla, Tomáš; Zlámal, Petr
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
      The presented paper is focused on embedding of the serially manufactured piezo-electric impact loadcell into Open Hopkinson Pressure Bar (OHPB) and it’s modifications for a direct force measurement during dynamic loading. ...

    • EVALUATION OF HOPKINSON BAR EXPERIMENTS USING MULTIPLE DIGITAL IMAGE CORRELATION SOFTWARE TOOLS 

      Author: Adorna, Marcel; Brodner, Stefan; Falta, Jan; Zlámal, Petr; Fíla, Tomáš
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
      Three different tools for Digital Image Correlation (DIC) were used for evaluation of dynamic experiments performed using custom Open Hopkinson Pressure Bar (OHPB) apparatus. High strain-rate measurements were performed ...

    • HIGH STRAIN-RATE COMPRESSIVE TESTING OF FILLING MATERIALS FOR INTER-PENETRATING PHASE COMPOSITES 

      Author: Doktor, Tomáš; Fíla, Tomáš; Zlámal, Petr; Kytýř, Daniel; Jiroušek, Ondřej
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
      In this study behavior of the selected types of filling material for the inter-penetrating phase composites was tested in compressive loading mode at low and high strain-rates. Three types of the filling material were ...

    • IN-SITU COMPRESSION TEST OF ARTIFICIAL BONE FOAMS IN CONTROLLED ENVIRONMENT USING X-RAY MICRO-COMPUTED TOMOGRAPHY 

      Author: Glinz, Jonathan; Kytýř, Daniel; Fíla, Tomáš; Šleichrt, Jan; Schrempf, Andreas; Fürst, David; Kastner, Johann; Senck, Sascha
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
      In this study, we investigated specimens of artificial bone foams, developed by the research group for surgical simulators at the UAS Linz, which are used to mimic the haptic feedback of physiologic and pathologic bone for ...

    • NUMERICAL MODELLING OF WAVE SHAPES DURING SHPB MEASUREMENT 

      Author: Dvořák, Radim; Koudelka, Petr; Fíla, Tomáš
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
      The paper aims at the numerical simulation of the wave propagation in compressive Split Hopkinson Pressure Bar (SHPB) experiment. The paper deals with principles of SHPB measurement, optimisation of a numerical model and ...

    • STRAIN-RATE AND PRINTING DIRECTION DEPENDENCY OF COMPRESSIVE BEHAVIOUR OF 3D PRINTED STAINLESS STEEL 316L 

      Author: Neuhäuserová, Michaela; Koudelka, Petr; Falta, Jan; Adorna, Marcel; Fíla, Tomáš; Zlámal, Petr
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
      The paper is focused on evaluation of the relation between mechanical properties of 3D printed stainless steel 316L-0407 and printing direction (i.e. the orientation of the part which is being printed in the manufacturing ...
