When the blood flow is analyzed numerically, the blood vessel is generally modeled with an elastic body or a comparatively simple viscoelastic model. Recently the computational method which takes a more complex generalized viscoelastic model has been developed as one of the methods of doing the numerical analysis of the cardiovascular system. As a result, it is understood that the viscoelasticity is a matter that cannot be disregarded as a characteristic of the blood vessel. However, only when pressure is assumed as much lower than human blood pressure, the numeric calculation is effective. Therefore, in this study, viscoelasticity property of a silicon tube, which is a polymer and has similar characteristics to the blood vessel, has been examined when a high pressure is applied to the tube.
