Abstract:	Using a non-Newtonian mathematical model for the blood flow in large vessels – elaborated and presented already by us in some previous papers we make some remarks on the wall shear stress (WSS) in the case of a human abdominal aortic aneurysm (AAA). We focused on the mechanical conditions which would lead to the rupture of the vascular vessel with aneurysm. The original feature is that the established condition is not backed on the real blood flow but only on the data got via the above mentioned model. This leads to a more suitable tool of risk rupture prediction which avoids almost completely the investigation in vivo.
Keywords:	wall shear stress, aneurysm, stress tensor, non-Newtonian model, rupture risk
