Abstract

In this study fluid-structure interaction for the carotid artery based on the experimental stress-stretch curves is presented. Experimental determination of carotid artery properties by using strips of human carotid artery is firstly performed. The strips were taken in the longitudinal and in the circumferential directions assuming that the carotid artery wall has the orthotropic characteristics. The material was subjected to uniaxial tension and the stress-stretch curves were obtained for various rates of deformation. It was found that the rates do not have significant effects on the passive response of the material. We employed the measured non-linear stress-stretch dependence to determine the coefficients in the analytical form of this dependence by a standard fitting procedure. Description of the numerical procedure, considering the carotid artery as a thin-walled shell structure subjected to blood pressure was given. Some results for the carotid artery model by solving coupled problem interaction between artery walls and fluid blood pressure are presented.
