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.

The usage of Salome Meca workbench for task solution in the field of solid mechanics
Anděl, Tomáš ; Návrat, Tomáš (referee) ; Vosynek, Petr (advisor)
Presented bachelor’s thesis focuses on solving basics tasks in the field of solid me-chanics by the finite-element open-source software Salome Meca. The theoretical background of finite element method (FEM), general explanation of basic expressions and brief summary of today’s used open-source and commercial software too is intro-duced in the opening part of the thesis. The brief overview of Salome Meca compu-ting environment and then file of individual tasks solved by using this software are followed. Acquired results are later compared with the other numerical software (ANSYS Workbench) or with analytical solutions.

The usage of Salome Meca workbench for task solution in the field of solid mechanics
Nytra, Michal ; Návrat, Tomáš (referee) ; Vosynek, Petr (advisor)
Submitted bachelors thesis deals with solution of tasks of body mechanics in open-source workbench Salome Meca and FEM solver Code_Aster. In the beginning is short theoretical introduction to finite element method a basic theory to strength of materials. Then follows series of tasks, which will test solver and workbench. We will compare results with analytical solution (if exists), eventually with available commerical software Ansys. There are 3 static structural tasks (beams, axisymetric bodies). Next task is from dynamics, searching of natural frequencies and vibration of plate during harmonic excitation. The last one is steady-state-thermal combined with static structural. In the conclusion are summarized advantages and disadvantages of open-source softwares. Results of workbench Salome Meca vary from analytical solution maximal to 10 %, what is in engineering praxis suffcient accuracy.

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.
