Economic and Technical Analysis of the Photovoltaic Facade System
Bónová, Kateřina ; Žák,, Antonín (referee) ; Hlavinková, Vítězslava (advisor)
This thesis comprehensively analyses photovoltaic power plants on facades both from economic and technical point of view. It also devotes to a broader view upon a photovoltaic power plants regarding their placement, its accessories and legislative. The thesis describes a calculation of energetic gains in details including evaluation of five solar radiation sources in order to assess energetic effectivity of the photovoltaic equipment. Furthermore, the thesis describes a means of determination of photovoltaic revenues which is closely related to its ability to sustain the energetic demand of the building. These calculations are presented in the conclusion of thesis where they are applied to four selected buildings. The thesis also contains a processed graph due to which it is possible to specify optimal size of photovoltaic facade. The size is depending on selected facade cardinal point orientation and also on floor area of the building, which serves to estimate future electricity consumption.

Crack path calculation using linear elastic fracture mechanics
Bónová, Kateřina ; Malíková, Lucie (referee) ; Eliáš, Jan (advisor)
This diploma thesis deals with the different possible calculations of crack path. Specifically, it focuses on criteria based on maximum tangential stress, minimal strain energy density, crack tip displacement, and local symmetry. These criteria are used for calculations in ANSYS software to estimate possible crack paths on four simple structures. The thesis also contains the codes created in ANSYS. Using these, the crack trajectory of a given structure can be calculated by any of the four criteria described.

Analysis of crack propagation using J-integral
Bónová, Kateřina ; Květoň, Josef (referee) ; Eliáš, Jan (advisor)
The bachelor thesis is focused on importance and application of J-integral in crack propagation analysis. J-integral is a method of fracture mechanics used to determine the strain energy release rate. In other words it provides the amount of energy available for crack propagation in elastic and elasto-plastic materials. The thesis presents derivations of relations between J-integral, crack driving force and stress intensity factor. The most important contribution of this thesis is detailed analytical calculation of the J-integral on simple structures. The results are verified by numerical models in ANSYS.
