A New Approach on the Strain Energy Function for the Mechanical Behavior of Arteries

Hakan Erol, Hasan Selim Şengel


In this study, a new constitutive equation that includes the characteristic nonlinear anisotropic response of arteries is proposed. The measurement of the relationship between arterial diameter and arterial pressure is important part of the general problem of blood flow measurements. This relationship was examined in the human thoracic aorta. The clinical data that obtained from literature provide only a pressure-diameter relationship. To determine the parameters of the constitutive formulations, nonlinear regression analysis was used on these data.
