Novel experimental methods to characterize the mechanical properties of the aorta

Nouvelles méthodes expérimentales pour caractériser les propriétés mécaniques de l'aorte

Résumé

Biomechanists have studied the mechanical properties of the aorta for more than five decades. Most experimental efforts have focused on characterizing the elastic and fracture properties using uniaxial or biaxial tests. Nowadays, the multiscale characterization of aortic mechanics is of crucial importance for mechanobiology. Techniques addressing the need for multiscale characterization are based on digital image correlation and digital volume correlation. They have become popular in soft tissue biomechanics for about a decade. In this chapter, we highlight the potential of these techniques in combination with optical coherence tomography imaging to quantify three-dimensional local strains in the aorta during uniaxial and biaxial testing and even to investigate fracture. Such investigations open up new perspectives to better understand the pathological mechanisms underlying aortic dissections.
