Wear regimes of aluminium alloys
Slivka, Václav ; Zapletal, Tomáš (referee) ; Šperka, Petr (advisor)
This thesis deals with the research of the wear regimes of the selected aluminium alloy in the conditions of dry friction. The aim of this work is the evaluation of the measure of an abrasive and adhesive wear of this alloy. This evaluation is made from the experiments which are made on the base of the knowledge of the research study. The dependence of the wear on the sliding speed and load, the friction on the sliding speed and load and the dependence of the normalised pressure on the normalised speed, so called the map of wear, are given on the base of the results of the measure.

Stress-strain behaviour research of rocks under dynamic loading
Petroš, V. ; Bagde, M. N. ; Daněk, T. ; Hofrichterová, L. ; Hudeček, V. ; Michalčík, P. ; Slivka, V. ; Špinka, O. ; Vavro, M. ; Žůrek, P. ; Holub, Karel
The aim of this project was oriented to determination of physical-mechanical characteristics of rocks under dynamic load using laboratory device MTS 816 Rock Test System. The research was drawn to investigation of surrounding rocks properties, i.e. rocks from the rock massif, where anomaleous geomechanical events do occur.
