MODELING ARTERIES AS A MULTILAYERS DILATATION ELASTICITY MEDIUM: A NUMERICAL INVESTIGATION

Abstract

Understanding the deformation of arterial walls under loading is essential for the definition of some new therapeutic protocols. This requires the modeling of the mechanical behavior of the artery wall. In this work, in order to account for the microstructure, each of the conventional three layers of the artery is assumed to behave like a dilatation elastic solid. The resulting compound is then submitted to various loads and the response analyzed in order to highlight the contribution of the microstructure. Finally, the impact of a localized zone of microstructure modification on the overall deformation is investigated.
