The Steel Structure of the Car Schowroom
Pelechová, Denisa ; Šmak, Milan (referee) ; Buchta, Stanislav (advisor)
The master’s thesis treat of design and appreciation load-bearing steel structure of Motor Show. The object is situated on the lokality Brno. Structure is composed of rolling sections and tubes. Overall height of the structure is 17,395 meters and overall lenght is 32,60 meters. Cross link iscomposed of arched girders panel that are supported on fixed pillars. Theoutside links are composed of panel columns. Load is composed of self weight, additonal imposed load, payload and climate load caused by wind and snow that is reached for given locality.Static rewiew comes out from previous load and it has been accomplished by Scia Engineer 2008 and hand computation.

The Tool for a Radial Expanding of Tubes by Liquid
Horák, Michal ; Lidmila, Zdeněk (referee) ; Peterková, Eva (advisor)
The submitted diploma thesis is focused on problematic of a radial expanding of tubes. In the first part of thesis, there is a summary of possible theoretical formulas for determining the stress-strain material parameters for biaxial bulging test of tube by liquid. Also there are showed several options for testing tools used in research abroad. The work also contains technological and control calculations for the selected test sample from the tube of steel 17 240 (1.4301). At the end of thesis, there are key points for tool design and there is also presented the proposed the test tool for a radial expanding of test sample of tube to the free space and with firmly fixed the ends of tube in the tool.

Analysis of Tube Bulging Process
Zdráhala, Radim ; Císařová, Michaela (referee) ; Peterková, Eva (advisor)
The diploma thesis is focused on the analysis of the behavior of the thin-walled tubular test specimen during the technological test of the liquid draining of the tubes. The test specimen ‘in the form a tube was made of austenitic stainless steel 17 240 (1.4301, X5CrNi18-10). During the experiment, the radial expanding tool was quasi-statically charged by the internal fluid pressure. In the introductory part, the thesis focuses on the stress-strain description of the method of tube bulging and possible ways of detecting the strain of material during forming. The experimental part is primarily focused on the analysis of the test sample that was obtained from the experiment. Theoretical approaches were used to analyze the real test sample to detect strain and stress in material, numerical simulation of the bulge process and 3D ATOS scanning device, which helped clarify behavior tube during bulging process. At the end of the thesis is proposed possible design of the tool. This modification should contribute in the future to the full functionality of the radial expanding tool, or the bulging of the tube by liquid.
