Effect of strain rate on the mechanical properties of materials
Gajdošík, Matej ; Forejt, Milan (referee) ; Jopek, Miroslav (advisor)
Metóda Taylorovho testu je využívaná na skúmanie vlastností materiálu za podmienok dynamického zaťažovania. Práca predstavuje kompletný proces vývoja, montáže a testovania nového testovacieho zariadenia zameraného na dosiahnutie symetrického nárazu dvoch vzoriek materiálu v pohybe. Zariadenie je testované v dvoch konfiguráciách, pričom sú opísané výsledky oboch. Boli vykonané materiálové testy smrekového dreva, ktoré boli následne porovnané s výsledkami získanými z klasického Taylorovho kanóna. Boli zistené a opísané podstatné rozdiely. Ukázalo sa, že vykonané simulácie symetrického nárazu s využitím modelu smrekového materiálu nezodpovedajú praktickým experimentom, čo naznačuje potrebné zmeny modelu.

Damascus steel production
Gajdošík, Matej ; Harant, Martin (referee) ; Podaný, Kamil (advisor)
Bachelor thesis deals with production of Damascus steel. Literary pursuit deals with methods of production, with closer elaboration of free forging technology, suitable material properties and work procedures during forging and etched specimen preparation. In the practical part of the work, production of two forged pieces consisting of 15n20, 80CrV2 and 1095 steels was documented. Subsequently an etched specimen was prepared to assess the success of the experiment. Finally, a knife was made from the selected forged piece.
