Comparative Study of Aortic Wall Stress According to Geometric Parameters in Abdominal Aortic Aneurysms

In abdominal aortic aneurysm (AAA), the rupture of tissue is directly related to wall stress. Thus, investigation maximum stress a necessary procedure predict in AAA. this study, computational simulations were performed investigate correlation between peak (PWS) and AAA geometry. The Holzapfel model various orientations collagen fibers thicknesses layers aorta employed simulation. material constants used estimated from examination analysis biaxial tensile test results normal diameter, height, neck angle, iliac angle selected as geometric factors affecting rupture. addition, simulation scenario was conceived created based on measurement using computed tomography data patients with Accordingly, PWS geometry estimated.
