Abstract: Aneurysm rupture is a biomechanical phenomenon that occurs when the mechanical stress acting on the inner wall exceeds the failure strength of the diseased aortic tissue. Besides numerous advantages in surgical and anaesthesiological management, emergency procedure leads to fatal outcome in 20-50% of those who reach hospital. Prediction of influence of dynamic blood flow on natural history of aneurysmatic disease and outcome of therapeutic procedures could contribute to treatment strategy and results. In this study we presented experimental design for estimation of the material property of real human aorta tissue from bubble inflation test. Then we investigated fluid-structure interaction of pulsatile blood flow in the specific patient three-dimensional model of abdominal aortic aneurysms (AAAs). Numerical predictions of blood flow patterns and nonlinear wall stresses in AAAs are performed in compliant wall anisotropic model using the finite element method. These computational procedures together with experimental determination of the nonlinear material property could provide us more accurate assessment of aneurysm rupture risk. © 2013 IEEE.
