Influence of residual stress on pressure vessel part fatigue life
Boleloucký, Václav ; Vincour, Dušan (referee) ; Létal, Tomáš (advisor)
This bachelor’s thesis deals with the impact of a residual stress, caused by an applied cyclic pressure, on fatigue life of a pressure vessel part (flat end–cylinder connection). Bachelor’s thesis includes the design of the pressure vessel according to CSN EN 13 445 regulations, analytical solution in Maple software, from which stresses and deformations are determined. Then the results of the analytical approach are firstly verified by a FEM modelling in ANSYS Workbench software and secondly compared to each other in graphs and discussed. From the values of stresses in FEM, analysis fatigue life expectations are calculated with the respect to CSN EN 13 445 regulations, for two cases. First one, where a pressure test is applied and second one, where the pressure test is not applied before the pressure vessel is put into service. In the conlusion the obtained results are discussed.

Sugar storage tank
Kotík, Libor ; Musil, Jiří (referee) ; Zich, Miloš (advisor)
The matter of this thesis is static design and examination of prestressed storage tank to 50000 tons of sugar. Computational model of the steel roof structure is processed and its effect on the silos. Loads is provided of sugar. Optimal design is performed and assessment ultimate and serviceability limit state reinforced concrete and prestressing horizontal silo wall including local load. Next, it is performed the design of a reinforced concrete of the plane bed and column and assessment at the ultimate limit state. The thesis is also drawing documentation, technical report and visualization of construction process. The aim of this work is to the design of the main components based on the required storage capacity tank, mechanical properties of the stored material and technical amenities.

Calculation of heatexchanger
Kvapil, Matěj ; Naď, Martin (referee) ; Klučka, Ivan (advisor)
This bachelor thesis focuses on strength calculation of a heat exchanger according to ČSN EN 13445. First stage is an introduction into the theme of heat exchangers and their calculation. Next part is about the calculation according to ČSN EN 13445 itself. Part of this thesis is also strength analysis of selected items using numerical method (FEM). Annexes include calculation in software Microsoft Excel and basic drawings of items.
