FRACTURE BEHAVIOR OF FeAlSi INTERMETALLICS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)
The study is devoted to the intermetallic alloy FeAl20Si20 (wt.%) with the potential applications in high temperature aggressive environments. The samples of the same chemical composition were prepared by spark plasma ...
COMPRESSION OF ECAPED TITANIUM MICRO-PILLARS FOR TWO PRINCIPAL ORIENTATIONS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)
The thermomechanical processing by equal-channel angular pressing (ECAP) is used for certain metals and alloys in order to make their structure fine and to increase material strength. In the previous study done at our ...
ROLE OF FLUID ON THE CONTACT DEFORMATION RESPONSE OF BIOLOGICAL TISSUE
(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 ...
PRE-PROCESSING OF ADDITIVE MANUFACTURING INPUT FILES FOR NUMERICAL SIMULATION
(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 ...
THECOMPARISON OF TWO DIFFERENT SPORTING EVENTS BASEDONTHETYPICALBEHAVIOROFTHEACTIVE SPECTATORS AND GRANDSTAND VIBRATIONS INDUCED BY THEM
(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, ...
MATHEMATICAL MODELING OF EXPERIMENT ON BERKOVICH NANOINDENTATION OF ZRN COATING ON STEEL SUBSTRATE
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)
In the present paper the experiment on Berkovich nanoindentation of ZrN coating on steel substrate is modelled using the proposed effective mathematical model. The model is intended for describing the experiments on ...
MECHANICAL PROPERTIES OF FORGED TUNGSTEN HEAVY ALLOYS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)
Tungsten heavy alloys are composite materials containing spherical tungsten particles embedded in binder matrix. Their excellent mechanical properties can be further improved by rotary forging. This paper aims to gain ...
EXPERIMENTAL STUDY OF DAMAGED CR-COATED FUEL CLADDING IN POST-ACCIDENT CONDITIONS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)
To enhance the safety of nuclear power, the focus of researchers all around the world has recently mainly objected on the development of Accident Tolerant Fuels. Especially the Chromium coating of current Zirconium based ...
NANOINDENTATION OF HYDROGEN ENRICHED Zr-1Nb ZIRCONIUM ALLOY NUCLEAR FUEL CLADDINGS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)
Zirconium alloys are being commonly used as a material of choice for nuclear fuel claddings in water cooled nuclear reactors for decades due to their good corrosion resistance and low neutron absorption. However, the ...
INDENTATION SIZE EFFECT IN HIGH PRESSURE TORSION PROCESSED HIGH ENTROPY ALLOY
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)
High entropy alloy HfNbTaTiZr in as cast conditions and after high pressure torsion straining was characterized by nanoindentation. The length-scale dependent material response (indentation size effect) was characterized ...
