TI - Biomechanics of Abdominal Aortic Aneurysms: Flow-Induced Wall Stress Distribution T2 - The International Conference on Computational \& Experimental Engineering and Sciences PY - 2007 VL - 1 IS - 1 SN - 1933-2815 AB - Abdominal aortic aneurysm (AAA) rupture is believed to represent the culmination of a complex vascular mechanism partially driven by the forces exerted on the arterial wall. In the present investigation, we present fully coupled fluid-structure interaction (FSI) and finite element analysis (FEA) computations of a patient-specific AAA model. This work advances previous FSI AAA modeling by including localized intraluminal thrombus and the comparison of FSI- and FEA-predicted wall stress distributions. The FSI transient fluid and wall dynamics resulted in a maximum wall stress 21% higher than that obtained with FEA, demonstrating the importance of modeling blood flow for the assessment of AAA wall mechanics.
