	Mechanical Properties of Hydrogels - Comparison between DMA and AFM Measurements of Elastic Modulus Hofrichterová, Tereza ; Valentová, Helena (advisor) ; Shukurov, Andrey (referee) Polymer hydrogels consist of polymer network that is able to absorb large amount of water. They have plenty of real-life applications - for example in medicine and diagnostics. The aim of this thesis is to study elastic modulus of several hydrogel samples by two different methods - dynamical mechanical analysis (DMA) and atomic force microscopy (AFM). Dynamical mechanical analysis represents a traditional method, which is expected to supply very reliable data. On the other hand - there has not been done much research in the field of studying mechanical properties with atomic force microscopy yet. This thesis should result into comparison of these two methods and describing effects that influence the measurement. Detailed record
	Fatigue properties of magnesium alloy AZ31 prepared by rotary swaging method Hofrichterová, Tereza ; Drozd, Zdeněk (advisor) ; Trojanová, Zuzanka (referee) Magnesium alloys are considered to have a high potential for applications in many engineering fields. Specifically, AZ alloys are of low weight, good castability and strength and they are also fairly resistant to corrosion. Moreover, the mechanical properties can be further improved by metalworking tech- niques. Methods of severe plastic deformation are often used for this purpose. Rotary swagging, which is one of those methods, is used for tubes and rods crafting. This method allows the material structure to reach homogeneous microstructure in its full volume. There has already been a fine amount of research effort and studies done in regards to mechanical properties of AZ alloys prepared with the methods of severe plastic de- formation. The ultimate goal of this thesis is to study fatigue properties of said alloys, which have not been subjected to such research in sufficient volume as of yet. 1 Detailed record
