Inverse methods for characterizing the anisotropic hyperelastic behaviour of arteries in vitro

Abstract

In this paper, we present a bi-axial characterization of in vitro human arteries. From the full-field experimental data obtained in inflation/extension tests, an inverse approach, called the virtual fields method (VFM), is used for deriving the material parameters of the tested arterial segment. The obtained results are promising and the approach can effectively provide relevant values for the anisotropic hyperelastic properties of the tested sample.
