Stress-strain analysis of chosen pipe flange
Pařízek, Daniel ; Poduška, Jan (referee) ; Novák, Kamil (advisor)
The bachelor's thesis deals with stress-strain analysis of chosen type of pipe-flange. The chosen type was a Weld-Neck flange, normalized according to European standard EN 1092-1+A1. Initially, the pipe-flange is modelled as a composed solid body, using available analytical theories of thin-walled axisymmetric shells and plates. Then, the stress-strain analysis is performed using FEM software Ansys. In the end, the applicability of obtained analytical results is discussed, compared to the exact numerical solution.

DAMAGE OF COMPOUND STRUCTURES CAUSED BY MATERIAL DISCONTINUITY
Korbel, Jakub ; Žmindák, Milan (referee) ; Hutař, Pavel (referee) ; Knésl, Zdeněk (advisor)
This Ph.D. thesis deals with modeling of compound structures containing defects such as cracks or notches. Attention was mainly focused on structures manufactured out of metals and polymers. Presented results were obtained from experimental measurements, which were compared with theoretical estimations of the ultimate states of the compound structures. Theoretical estimations were obtained by the application of the generalized fracture mechanics, whose integral part is based on numerical solution provided by finite element method. The results of the Ph.D. thesis contribute both to prediction of the limit states of compound objects, and to verification of the validity of the generalized fracture mechanics.
