Stress-strain analysis of anastomosis between artery and artificial vascular graft
Hrubanová, Anna ; Švancara, Pavel (referee) ; Burša, Jiří (advisor)
This bachelor’s thesis deals with anatomy and pathology of arteries and possibilities of their replacement with vascular grafts. The first part of the thesis describes structure and mechanical properties of arterial wall. Furthemore, the biological and mechanical properties of vascular grafts and their influence of healing process are described. The second part of this thesis starts with non-linear calculation of deformation of arterial wall using generalized Hooke’s law. The analytical calculation of connection of artery and vascular graft using cylindrical momentum shell theory was made at the end of this thesis. Description of limitations of this method is also included.

Influence of mechanical properties of vascular grafts on their clinical applications
Chomič, Dimitrij ; Polzer, Stanislav (referee) ; Burša, Jiří (advisor)
The theme of my bachelor’s thesis is the vascular replacement. I write about the types of blood vessels, their anatomy, physiology, pathology and mechanical characteristics. My thesis contains a part about the types of vascular replacements, I define their mechanical characteristics and I describe how the vascular replacement used in medicine. I study the artificial vascular replacement preferentially. To illustrate the application of the moment theory of cylindrical shells (Course in PP II), I solve the extreme stresses in the connection of a replacement with a vessel having mutually different geometrical and material parameters. The artery and the replacement were under pressure of 16 kPa corresponding to the systolic blood pressure.
