Footbridge across the river Bečva
Totková, Lucie ; Glovina, Filip (referee) ; Nečas, Radim (advisor)
The aim of this thesis is the design of curved footbridge across the river Bečva. Curved footbridge consists of a supporting steel arch, which brings the steel struts to the steel arch under the concrete deck. The steel arch with crosspieces is coupled with concrete deck using the coupling pins. The deck is formed from reinforced concrete. Structural model is carried out in a computer program ANSYS. The structural design is handled in accordance with applicable European standards. The design considers pedestrians load and temperature effects.

Stress, deformation and safety analysis of the tandem bicycle frame
Profota, Martin ; Dobeš, Martin (referee) ; Vrbka, Jan (advisor)
Purpose of this work was the evaluation safety and pliancy of the frame structure tandem bicycle using method of basic elasticity with the help of the deformation and stress analysis. After introduction material and geometry of the frame tandem bicycle introductory part is focused on theoretical basis of calculation like beam assumptions, definition the beam, limit states, Sentence of Castigliano and Saint Venant's Principle. Before commencement actual analytical solution the spatial task was transferred to plane task and used model was simplified. Calculation related to two load states differing by way of load of frame tandem bicycle. For each load modes comparison with numerical solution by FEM was enabled. Mathematical software like Mathcad 14 and Maple 13 were used to analytical calculation. Check was performed by numerical solution in program ANSYS Workbench 14.5.

Modern cutting tools for grooving and cutting-off
Matoušek, Jan ; Fiala, Zdeněk (referee) ; Píška, Miroslav (advisor)
The thesis in question deals with the influence of geometry of the cutting tool with a non-null angle r and of the cutting conditions on change of cutting tool’s overall deformation during the process of cutting-off and grooving. When conducting the experiments the loading of cutting tool was measured, there was created a simple 3D model of the cutting tool based on measured data, the deformation analysis of the cutting tool by the simulation programme ANSYS was performed and on the grounds of established facts there was made a conclusion on attributes of the cutting tool during the process of cutting-off and grooving.

Analysis of methods of modeling bone loss due to osteoporosis
Orlová, Lucie ; Marcián, Petr (referee) ; Vosynek, Petr (advisor)
Tato bakalářská práce se zabývá biomechanikou kosti. Hlavním cílem je teoretický průzkum řešení pro výpočtové modelování dlouhých kostí a změn této struktury vlivem osteoporózy. V rámci rešerše jsou vysvětleny související biologické pojmy a základní principy mechaniky. Na základě informací shromážděných v teoretické části práce jsou provedeny výpočty pomocí metody konečných prvků v programu ANSYS.
