Stress-strain analysis of a bar systems using finite element method
Fodor, Ján ; Fuis, Vladimír (referee) ; Návrat, Tomáš (advisor)
The aim of this bachelors thesis is primarily programming of algorithm for solving bar systems (i.e. trusses) using finite element method. Programming language Python and his modules NumPy, SciPy and Matplotlib are used . The results thus obtained are verified in the program ANSYS . This work also gives a brief overview of commercial and freely accessible scientific software. Finite Element Method is a numerical method used for solving technical problems in mechanical engineering, structural engineering, electrical engineering and related fields.

Optimization of Flat House Heating
Fodor, Ján ; Baláš, Marek (referee) ; Lisý, Martin (advisor)
This diploma thesis deals with the supply of heat in a particular block of flats in Brno. It deals with supply for heating and for hot water heating. The introduction gives information about the considerated building and also generally, but especially with regard to the current situation with consumption and heat supply. Subsequently, the thesis describes the individual possibilities of obtaining heat. There are mentioned classical heat sources as gas boilers, but also less commonly used as co-generating units or solar collectors. Furthermore, the work is calculating from the technical and economic point of view for heating options chosen by the investor. Finally, the work compares the options from viewpoint of benefits, budgets and returns of possible investments.

Assessment of investment in heating house
Fodor, Ján ; Lisý, Martin (referee) ; Baláš, Marek (advisor)
The bachelor’s thesis focuses on the assessment of individual investments for reducing the costs of heating a house. Firstly a heat loss of building was calculated according to norm ČSN EN 12831. Then were proposed some steps to save heating costs. Finally, it was in thesis economic confrontation individual’s steps for decreasing costs and their mutual confrontation.

Determination of the mechanical properties of the multilayer structure materials with utilization of the sonic resonance method and modal FE analysis
Fodor, Ján ; Lošák, Petr (referee) ; Ševeček, Oldřich (advisor)
Thesis deals with determination of layerwise mechanical properties of composite ceramics by indirect method, namely Youngs modulus. Based on literature review, it was found that a method to determine elastic properties of one or more components of multi layered composites based on experimental modal analysis and finite element modal analysis, or analytical approach exists. Method based on FE modal analysis was applied to ceramic laminate, where it was attempt to determine youngs modulus of one component. Beyond that, it was attempt to determine Youngs moduli of both components using first two bending resonant frequencies. Results were unsatisfying. Sensitivity analysis showed that layers with unknown Youngs modulus were overly sensitive to small changes in input parameters due to their small relative thickness with respect to thickness of laminate and due to location in laminate. Based on this conclusion, recommendations were made with respect to suitable geometry of test specimens.
