Using Salome Meca computing environment to solve problems of solid mechanics
Ptáček, Tomáš ; Vaculka, Miroslav (referee) ; Vosynek, Petr (advisor)
Given bachelors thesis deals with solutions of basic tasks of body mechanics with usage of the finite element method (FEM). An open-source software Salome Meca with Code_Aster solver is used there. Basic formulas of strength of materials on which is FEM based are introduces in the beginning. Then is presented software Salome Meca with its solver Code_Aster. Followed by own solution of tasks, which contain structural analysis and series of examples for solving the fracture mechanics. Numerical solutions from Salome Meca are compared with analytical solutions, if some exist, and with solutions from commercial software Ansys Workbench.

Analysis of the use of Code_Aster in solving the limit state of fatigue strength
Busta, Michal ; Kovář, Jaroslav (referee) ; Vosynek, Petr (advisor)
This bachelor’s thesis deals with the analysis of the use of Code_Aster in the calculations of the limit state of fatigue strength. The first part is the research in fatigue analysis using the solver Code_Aster and in the second part the know-how of Code_Aster usage is used to solve three tasks of the limit state of fatigue strength. Acquired results are compared with analytical solutions and with the student licence of the numerical software Ansys Workbench 19.2. In conclusion, all the results are analysed.

Strength analysis of the steering lever
Klimeš, Henrich ; Blokeš, Jan (referee) ; Vosynek, Petr (advisor)
The bachelor's thesis deals with the estimation of the number of cycles to failure of the steering lever material, which occurs on some Tatra vehicles. The theoretical part describes the necessary tools to calculate the control lever. In the second part, a simplified stress estimation is performed by using analytical calculation. The analytical calculation is then verified in the freely available program Salome Meca, in which the actual stress calculation on the 3D model of the steering lever takes place.

Comparative analysis of light holder lifetime assessment methods
Holeta, Aleš ; Pokorný, Jan (referee) ; Vosynek, Petr (advisor)
This thesis addresses the topic of determining the fatigue life of a thin-walled holder fender and flashlight under variable loads. The aim of the thesis is to make a search study on the fatigue life of welded parts with respect to the thin-walled design of structures. The main objective is to evaluate the suitability of using different methods of fatigue life assessment on the holder fender and flashlight. The calculated fatigue lifetimes are confronted with experimentally obtained fatigue life-times. The fatigue lifetimes are determined by methods evaluating welded joints based on structural stresses and notch stresses. Finite element analysis was performed in the open-source programs Salome and Code_Aster. The modelling of the holder fender and flashlight geometry was performed at several levels. Based on the results, the most efficient method for the design of welded parts is the structural stress linearization method (also called “master S-N curve method”), which achieves comparable results to the effective notch stress method (considered as a reference), but with a multiply lower time consumption.
