Effect of spine on stresses in abdominal aortic aneurysm
 Lisický, Ondřej ; Horný,, Lukáš (referee) ; Polzer, Stanislav (advisor)
This thesis deals with stress strain analysis of an aortic abdominal aneurysm (AAA) and the influence of its contact with the spine on the extreme wall stress. The influence was tested on the idealized geometry, as well as on ten patient specific geometries obtained from computer tomography (CT-A) scans. Hyperelastic constitutive models were used for the AAA wall and intraluminal thrombus (ILT) tissue description. The prestress algorithm was used for reconstruction of the unloaded geometry to get more trustworthy results against the geometry from CT which was obtained under the blood pressure. Statistical analysis was used for the results evaluation. The maximal increase of peak wall stress was as high as 81 %.

Strain-stress analysis of the throttle valve components
 Lisický, Ondřej ; Vosynek, Petr (referee) ; Návrat, Tomáš (advisor)
This thesis deals with stress-strain analysis of component, which is used for regulation of gas quantity, which comes into gas boiler. There will be acquaintance with issue, determining load and consecutive application of this load in ANSYS. At the end there is a chapter pursuing of experiment on the component.
