Strain-stress analysis of membrane shells and influence of their fixing on origination of local bending moments
Méheš, Libor ; Skalka, Petr (referee) ; Ševeček, Oldřich (advisor)
The bachelor's thesis deals with a stress-strain analysis of spherical and toroidal membrane shells. Both of these tasks are modeled based on real water towers. A literature review is conducted on the field of membrane shell theory, the utilization of shells, and their design. Parametric computational models were created for the purpose of analysis, both analytical in Matlab and numerical based on the finite element method in Ansys Workbench. These solution approaches and their results are properly compared and evaluated in the thesis. Special attention is paid to the possibilities of shell support with respect to maximum safety factor. The main outcome of the thesis is the design of the most suitable support system depending on the connection position, along with the creation of parametric models required for this analysis.
