Stress-strain analysis of skull implant using analytical and numerical solution methods
 Sehnal, Dominik ; Borák, Libor (referee) ; Marcián, Petr (advisor)
This thesis focuses on stress-strain analysis of cranial implant. The research of literature available dealing with the problems of cranium implants and the solution of the stress analysis is incorporated. Furthermore, the basic information about an approach to the design and fabrication of medical implants is included. Subsequently, two ways of possible solution to the method of stress-strain analysis on an computational model of cranium (partially spherical shell) are introduced. These are analytical and numerical solution by using the finite element method in the Ansys programme. The calculated solutions of a particular type of task about deformation and stress are compared and evaluated with the solution acquired from the high level computational model of cranium with shaped irregular implant applied.

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.
