    • Analysis of surface defects in composites using digital image correlation and acoustic emission 

      Začal, Jaroslav; Dostál, Petr; Rozlivka, Jakub; Brabec, Martin (Mendelova univerzita v Brně, 2018)
      This work employs the acoustic emission (AE) method for material state monitoring. AE presents a non-destructive evaluation technique, which could be used for detection of microstructural changes in composite material. ...

    • CMT Welding of Titanium and Stainless Steel Using CuSi3 Electrode 

      Poláková, Nela; Dostál, Petr (Mendelova univerzita v Brně, 2019)
      The article deals with the possibility of a tight permanent joint of X5CrNi 18-10 austenitic steel and UNS N50400 titanium. The nuclear and chemical industries are in particular interested in solving this problem. The ...

    • Determination of grain size and resistance to corrosion of stainless steel welded pipes 

      Hudeček, Pavel; Dostál, Petr (Mendelova univerzita v Brně, 2017)
      Discover problems of welds is not so easy from time to time. Specially, If welding was made in rough environmental conditions such as high temperature, humidity and dusty wind. It is necessary to provide good conditions ...

    • Operational Degradation of Engine Oil in Agricultural Technology 

      Dostál, Petr; Rozlivka, Jakub; Kumbár, Vojtěch (Slovenská poľnohospodárska univerzita v Nitre, 2019)
      Proposed paper is focused on description and observation of operational degradation of engine oil in agricultural technology. Engine oil is one of the most important liquids used in combustion engines. Correct function of ...

    • Titanium and Stainless Steel MIG LSC Welding 

      Poláková, Nela; Dostál, Petr (Slovenská poľnohospodárska univerzita v Nitre, 2019)
      This paper deals with the issue of welding two different materials - titanium and stainless steel (UNS N50400 X5CrNi 18-10). These two materials have completely different chemical compositions and mechanical properties; ...

    • Use of acoustic emission for testing resistance of hooves 

      Dostál, Petr; Havlíček, Zdeněk; Kratochvílová, Lucie (Mendelova univerzita v Brně, 2018)
      This paper deals with the possibility of using an acoustic emission method for testing tensile strength of hooves. By using the acoustic emission (AE) method, we are able to locate degraded areas in hooves and then estimate ...
