An abdominal aortic aneurysm poses a significant risk of arterial wall rupture,which critically endangers the patient’s life. To address this condition, anendovascular aneurysm repair (EVAR) is required, involving the insertionand expansion of a Stent-Graft within the aorta, to support and isolate theweakened vessel wall. This thesis approaches the problem from a mechanicalperspective and aims to simulate the procedure realistically utilising theFinite Element Analysis (FEA) method. The study incorporates the necessarytheoretical background, identifies critical regions of stress and strain in ananeurysmatic aortic model, and provides detailed guidance for the 3D modelingof the Stent-Graft in Fusion 360. Furthermore, a complex non-linear analysisis conducted in the simulation environment of Ansys Mechanical. Finally,the mechanical behavior during the expansion process is evaluated, and theextracted results are analyzed and compared with real-world data. Overall,this study offers useful material for both educational and scientific purposesand lays a solid foundation for more advanced future research.
