Abstract

Artificial vessel graft is one of most common procedures. In order to prevent damaging the blood hemodynamic’ s, mechanical behavior of this prosthesis should be close to the natural blood vessel. The main goal of this study is to develop an adequate model for artificial blood vessel analysis and to use that model to design a good Artificial vessel with functionally graded material. In this study, geometry, three layer structure and pressure conditions of blood in ascending part of aorta have been modeled, and radial displacement versus time, radial displacement versus length, circumferential and von-mises stress have been obtained. After validating this simulation, two common materials for artificial blood vessel were used to design Functionally graded materials with different Heterogeneous indexes. After FSI simulation of Artificial vessel made of parabolic functionally graded material and natural vessel, response parameters for different Heterogeneous indexes were calculated and compared with the natural vessel behavior. Results of this study suggest that using a functionally graded material made of Dacron, Teflon and Polyurethane with intermediate Heterogeneous index shows a close behavior to the natural blood vessel.
