Analysis of fracture of quasibrittle materials using numerical modelling and acoustic/electromagnetic emission
 Vodák, Ondřej ; Vořechovský, Miroslav (referee) ; Veselý, Václav (advisor)
This master thesis gives overview of non-destructive tests of concrete and provides detailed information concerning the acoustic and electromagnetic emission during monitoring of concrete failure. Conducted loading tests of plain concrete specimens are described in the thesis together with the performed numerical simulations of these tests in the software ATENA. The simulation results of concrete failure are analysed in detail and compared with the experimental results recording failure processes with the help of acoustic and electromagnetic emission. The majority of simulation results in software ATENA 3D show good agreement with the recorded data.

D - Areas Analysis using Strut and Tie models
 Konárek, Lukáš ; Hradil, Petr (referee) ; Zídek, Rostislav (advisor)
The objective of bachelor thesis is the analysis of typical D-areas of reinforced concrete structures. The analysis is performed using methods replacement truss. In the beginning models replacement truss are used for analysis shear bending girder. It is also shown in the individual chapters specific D-areas using spare truss method. These particular truss models are solved by RFEM program operating on the principle of Finite Element Method.
