The effect of plastic strain of the reinforcement of aircraft panel made from aluminium alloy on the corrosion process
Valoušek, Tomáš ; Tulka, Jaromír (referee) ; Pacal, Bohumil (advisor)
This bachelor thesis is focused on study of corrosion of reinforcement panel of aircraft in environment of salt fog. The reinforcement material is aluminum alloy AlZnMgCu1,5 after solution annealing, release stress relieving and artificial aging, can be slighly deformed to compliance limit deviation. Material is not provided with any coating. The aim was to find out what is the effect of plastic deformation on the corrosion behavior of this alloy. In the experimental part of this thesis were studied the size and type of corrosion attack of samples with different plastic deformation. These values were furhter processed, evaluated and were drawn from them conclusions.

Modal Analysis of the Blades Row Tied with Z-tie
Valoušek, Tomáš ; Chromek, Lukáš (referee) ; Lošák, Petr (advisor)
This thesis is about modal analysis of the rotor blades row tied with Z-tie. Thesis was solved by finite element system ANSYS. Cyclic symmetry was used in this thesis with the aim of obtain eigen frequency of bladed disc. The next aim of this thesis was to find eigen frequency of the free rotor blades and to compare it with frequency obtained from experiment. 3D model was created by 3D scanner and CAD system CATIA.
