Numerical analysis of a brain artery in ANSYS

Abstract

In the last decade, the brain arteries were a source of lot of research; many of them try to study from an engineering perspective difficult disease such as aneurysm. They usually choose either the blood or the artery to study, but few do both without any bigger considerations like considering blood Newtonian or the structure elastic. This study tries to give a different light to those by trying to study the nature of a brain artery. The brain arteries were treated as a fluid–structure interaction problem, for that was used a two-way coupling method between a non-Newtonian fluid and an isotropic hyperelastic structure. With this approach, conclusions about the nature of brain arteries could be made. Those conclusions could lead to new reflections about failure mode of arteries and the function of each artery layer.
