Abstract	Fluid-structure interaction analysis in Internal Carotid Artery(ICA) are carried out as preparation for validation between the result of numerical simulation and photoelastic stress analysis. In this work, we assume blood vessel as an isotropic elastic medium and the wall's Poisson ratio is 0.45 and Young's modulus is 3.0Mpa. Our study shows various parameter on fluid dynamics of blood flow, such as the velocity profile, wall shear stress distribution, displacement of vessel wall and Mises stress. Blood flow after bifurcation generate vortex flow and decreases flow speed and wall shear stress nearly to 0Pa. This low wall shear stress can accelerate the accumulation of plaque and eventually causes vessel narrowing. Moreover, the maximum wall shear stress and Mises stress is focused on the bifurcation of ICA. These high stress may lead to aneurysm initiation.
