Stress and deformation analyses of the bridge near the Jedov mill
Hort, Michal ; Kovář, Jaroslav (referee) ; Fuis, Vladimír (advisor)
Bridges serve to many people every day, so it is necessary to be concerned about theirsafety. Analysis of bridge superstructures are used to increase their safety - and this is also the mainsubject of this thesis. Specifically, it is the analysis of the pedestrian bridge located near Jedov Mill on the Oslava river. For the stress and strain calculations, the method of joints is used, and that iscompared with the finite element method. During the comparison of the methods which hadbeen used, it was found, that the method of joints is suitable for identifying critical points, but cannot accurately determine stress values. While the finite element method can both, identify critical locations and determine the exact stress values. These calculations determinedthe critical locations on the footbridge, which are in the outmost members of the structure. By enlarge their cross-section would increase the safety of the structure. Among the critical trusses do not belong trusses damaged by the footbridge crash. The safety factor of the pedestrian bridge to the elasticity limit state, which is k = 1.74, provides a sufficient reserve for the further use of the footbridge, even if the cross-sections of the above mentioned members are not increased.

Stress and deformation analysis of the stem and cup of the total replacement of the trapeziometacarpal joint
Svojanovský, Tomáš ; Vosynek, Petr (referee) ; Fuis, Vladimír (advisor)
The center of attention of this bachelor’s thesis is stress and deformation analysis of the total replacement of the trapeziometacarpal joint. The first part is formed by medical essence of the matter, namely from the anatomical and pathological point of view. The connecting link between literature research and analysis creates a short introduce to the finite element method. To the stress and deformation analysis itself was used the program ANSYS Workbench 14.5 based just on the finite element method. One of the purposes is to get to know this program and to learn to gain correct results. The main target is to catch and describe stress and deformation of the simplified model of a certain implant. Despite some of the simplifications, resulting values should approach to the real values. Except for the mentioned analysis, there are introduced different approaches, which could be used for the solution. There is also some comparison of advantages and disadvantages of particular approaches.
