    • IMPACT TESTING OF ORDNANCE GELATINE UNDER MODERATE STRAIN RATE CONDITIONS 

      Autor: Doktor, Tomáš; Zlámal, Petr; Šleichrt, Jan; Fíla, Tomáš; Kytýř, Daniel
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
      An experimental study on energy absorption capabilities and strain rate sensitivity of ordnance gelatine was performed. Strain energy density under quasi static compression and moderate strain rate impact tests was compared. ...

    • INSTRUMENTATION OF FOUR-POINT BENDING TEST DURING 4D COMPUTED TOMOGRAPHY 

      Autor: Kytýř, Daniel; Fíla, Tomáš; Koudelka, Petr; Kumpová, Ivana; Vopálenský, Michal; Vavro, Leona; Vavro, Martin
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
      High-resolution time-lapse micro-focus X-ray computed tomography is an effective method for investigation of deformation processes on volumetric basis including fracture propagation characteristics of non-homogeneous ...

    • MULTI-CHANNEL CONTROL SYSTEM FOR IN-SITU LABORATORY LOADING DEVICES 

      Autor: Rada, Václav; Fíla, Tomáš; Zlámal, Petr; Kytýř, Daniel; Koudelka, Petr
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
      In recent years, open-source applications have replaced proprietary software in many fields. Especially open-source software tools based on Linux operating system have wide range of utilization. In terms of CNC solutions, ...

    • PREPROCESSING OF HOPKINSON BAR EXPERIMENT DATA: FILTER ANALYSIS 

      Autor: Adorna, Marcel; Falta, Jan; Fíla, Tomáš; Zlámal, Petr
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
      This work presents a data preprocessing procedure for signal acquired during high strain-rate loading using a custom Split Hopkinson Pressure Bar (SHPB). Before the evaluation of the experimental data, preprocessing of the ...

    • TESTING OF HYBRID NICKEL-POLYURETHANE FOAMS AT HIGH STRAIN-RATES USING HOPKINSON BAR AND DIGITAL IMAGE CORRELATION 

      Autor: Adorna, Marcel; Zlámal, Petr; Fíla, Tomáš; Falta, Jan; Felten, Markus; Fries, Michael; Jung, Anne
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
      In this paper Split Hopkinson pressure bar (SHPB) was used for dynamic testing of nickel coated polyurethane hybrid foams. The foams were manufactured by electrodeposition of a nickel coating on the standard open-cell ...
