Due to recent changes in living conditions, people who suffer from vascular disease have been increasing. As a result, several kinds of procedures to treat diseases of the blood vessels are being carried out and the epidemiological analysis and interpretation is needed. In this paper, the mechanical behavior of blood vessels based on hyperelastic model were evaluated. The stress distributions in the arterial walls subjected to both normal blood pressure and high blood pressure are studied along with different opening angles representing as the effect of the residual stress. As a result, when applied to residual stress effects in blood vessels to act maximum stress compared to as the absence of residual stress effect about 50% stresses can be reduced. When high blood pressure was the normal blood pressure acting on the blood vessel wall that twice stress can be confirmed.
