Experimental Car for Testing of Combustion Engines
Dubský, Jiří ; Beran, Martin (referee) ; Svída, David (advisor)
The goal of this diploma thesis is to design a frame for an experimental vehicle. The primary object is to design a conception and layot of a drive unit. The frame design is followed by a creation of a model for an analysis. The model will serve for torsional stiffness computing using FEM analysis software. After evaluation of results additional chanhges of the design may take place. A vehicle will serve for testing combustion engines of the same conception and thus it is not intended to run on public roads.

Steel Structure of Footbal Grandstand
Kloss, Tomáš ; Pilgr, Milan (referee) ; Hron, Lukáš (advisor)
The aim of this bachelor´s thesis is to design and check the football grandstand roof construction with ground plan dimensions of 30 x 105 m and a height of 20.5 m. Climatic loading is determinated for the location of the construction site - Ostrava. The resulting structural system was chosen spatially co-composed of trusses, purlins trusses, transverse and longitudinal stiffeners, columns and struts. The shape of the roof, which commemorates the air wing, is creating difficult conditions for wrapping air currents. Parts of the work are: technical report, structural analysis of the main structural elements and selected connections and drawings. The computational model for determination of internal forces is implemented in Scia Engineer. The review is created manually according to valid European standards.

Influence of strain rate on stress-strain dependencies of aortic tissues
Slažanský, Martin ; Fuis, Vladimír (referee) ; Burša, Jiří (advisor)
The thesis deals with the influence of strain rate on stress-strain dependencies of aortic tissues to estimate the error of hyperelastic models, which are neglecting the viscoelastic effects that are typical for soft biological tissues. It was found by the experiment and the subsequent evaluation that in the range of the strain rate from 0,167 to 5,000 mm/s the influence of strain rate on stress-strain dependencies is negligible. The deviation by transition from experimental data to a constitutive model was significantly larger than the deviation between the data sets varying at different strain rates, which means that the use of stress-strain curves varying at different strain rates in given range of the strain rate has no effect on the resulting model. The best of analysis models that were examined in this thesis appears to be the Yeoh hyperelastic model using the FEM.
