Objective To study the properties of artery in different conditions. Method The different simulations of the aorta were made by the linear elastic model with small and large displacement, the nonlinear elastic model and the model with residual stress, respectively. We analyzed the circumference stress distributing and displacement distributing of the above four models by finite element method and made the comparison among them. Results It showed that residual stress changed the distribution of circumference stress but didn’t change the circumference stress level, and have no clear influence on the displacement of the aorta. Conclusion Because of the exist of residual stress, the stress concentration distributing along the blood wall.has obviously decreased.
