Abstract: The study on the non-linear elajstic properties of the arterial wall is a precondition forstudying of the fluid properties and the propagation of pulsatile wave in blood vessels. In studiesof blood vessels, there were a lot of researches on the constitution of the straight blood vessels.But, there is not a theoretical model for analyzing the non-linear elastic properties of the curvedblood vessels, like aortic arch. In this paper j based on the study of the constitution of straightblood vessels, we proposed...
