Finite Element Analysis for the Design of Branched Artificial Blood Vessel of Aortic Arch

In order to set up a curved-shape branch artery-blood coupling model and investigate the effect of the material change in artificial blood vessel on the hemodynamic state, the method of finite element and Fluid Solid Interface in Ansys CFX was used to achieve the structural and fluid analysis with different materials. The displacement of tubular wall was increasing with the young's modulus decrease of material, and the tendency became clear. The von mises stress of the tubular wall is not well-distributed, and the value at the inlet of main artery and branch artery were large. However, at the outlet of artery was small, and the von mises stress of tubular wall with different materials has little difference. Results show that, the hemodynamic state was different with different materials, and the finite element method is helpful to the design and preparation of artificial blood vessel.
