Abstract

The Fluid Structure Interaction (FSI) model of Abdominal Aortic Aneurysm (AAA) is developed to estimate wall stress value in abdominal aortic aneurysm. The One-way coupled transient FSI technique is used for the analysis. The geometry of AAA constructed from Computed Tomographic (CT) image data. The aortic wall is treated as linear elastic material. The pressure values from the transient Computational Fluid Dynamics (CFD) study of AAA were used as luminal pressure load on the aortic wall. The Peak Wall Stress (PWS) of 167.3 psi (113.04 N/cm2) is estimated from the model. The quantitative value of wall stress from this study could assist the physician in assessment of aneurysm rupture risk.
