Experimental data processing for calibration of isotropic hardening model
Chlaň, Jakub ; Kubík, Petr (referee) ; Šebek, František (advisor)
The main aim of the present bachelor's thesis is to create a universally applicable script, which is used for the data processing of the fatigue test in order to calibrate the isotropic hardening model. The theoretical part is devoted to the phenomenon of cyclic hardening/softening, the mathematical models of hardening and last but not least, the practice of fatigue tests together with the possibilities of their evaluation. The rest of the work includes the algorithm creation procedure and demonstration of its functionality by processing data from fatigue tests of alloy AlCu4Mg1.

Low cycle fatigue of EN-AW 7075 aluminium alloy
Bártková, Denisa ; Liškutín, Petr (referee) ; Věchet, Stanislav (advisor)
The main goal of this bachelor thesis is analysis of low-cycle fatigue of wrought alluminium alloy EN-AW 7075. In theoretical part of thesis, current facts about alluminium alloys and fatigue behaviour of material are summarized. Practical part contains evaluation of tension tests and analysis of experiments in low-cycle fatigue region. In additional, the microstructure of an alloy was observed.

Low Cycle Fatigue of Magnesium Alloy AZ91
Julišová, Martina ; Podrábský, Tomáš (referee) ; Juliš, Martin (advisor)
The objective of the present study is to investigate the fatigue characteristics of cast magnesium alloy AZ91 after low–cycle fatigue tests at the indoor temperature. Squeeze casting specimens in both non–thermal treatment cast state and in solution annealing state were used as the experimental materials. Cyclic hardening/softening and fatigue life curves were obtained from the tests varying according to the way of thermal treatment. This bachelor thesis includes also fracture tests of specimens. Light microscopy and scanning electron microscopy were used for the investigation.
