Evaluation of materials characteristics exploiting static and dynamical tests
Riesner, Jan ; Forejt, Milan (referee) ; Samek, Radko (advisor)
The project elaborated in frame of engineering studies branch M-STG describe characteristics of plasticity of non-anneal materials E 235, E 190 and E 220. Materials characteristic was receive by static and dynamical tests. Based on the literature study it was conducted survey of the current state of experimental techniques for high-speed deformation. The materials were designed by Holomon approximation of rigid-plastic material model without hardening. It was conducted force analyses for machine Unison MG 2790 for rewind bending and bend with compressive force considering the identified material model. It was describe the impact passive and active forces to move the neutral axis.

Expanding of tube ends
Riesner, Jan ; Šlais, Miroslav (referee) ; Peterková, Eva (advisor)
The project is elaborated within frame of bachelor´s studies of branch B2341-3. The project is submitting a summary of methods used for expanding of tube ends. In the first part on the basis of the studies of this problem there was created a set of methods which are used for expanding of tube ends. These methods are divided into three elementary parts according to the technology of production. Next part of this project describes modern methods in use. It is namely expanding of tube ends by radial jaws and method of expanded and towards the end renarrowing figures on the tube ends. In conclusion of this thesis there is treatise on quality checking of expanded tube ends and leakage test.
