Abstract
In the last decade the brain arteries were a source of lot of researches, many of them try to study from an engineering perspective very difficult diseases such as aneurysm. They usually choose either the blood or the artery to study, but few study both without some bigger considerations like considering blood Newtonain or the structure elastic. This study tries to give a different light to those by trying to study the nature of a brain artery. For that the behavior of the brain arteries were treated as a Fluid-Structure Interaction problem and for that was used a 2-way coupling method between a non-Newtonian fluid and an isotropic hyperelastic structure. With this approach some conclusion about the nature of brain arteries, and arteries in general maybe, could be made. Those conclusions could lead to some new reflections about failure mode of arteries and the function of each layer of an artery.
