Wall stress studies of abdominal aortic aneurysm in a clinical model

MJ Thubrikar, J Al-Soudi, F Robicsek - Annals of vascular surgery, 2001 - Elsevier
To estimate when an abdominal aortic aneurysm (AAA) may rupture, it is necessary to
understand the forces responsible for this event. We investigated the wall stresses in an AAA …

Mechanical stresses in abdominal aortic aneurysms: influence of diameter, asymmetry, and material anisotropy

JF Rodríguez, C Ruiz, M Doblaré, GA Holzapfel - 2008 - asmedigitalcollection.asme.org
Biomechanical studies suggest that one determinant of abdominal aortic aneurysm (AAA)
rupture is related to the stress in the wall. In this regard, a reliable and accurate stress …
