Publication Open Access Modelación por elementos finitos en un modelo de aneurisma(2014-04-20) Correa-Posada, S. (Santiago)Considering a model with generalized geometry and mechanical properties of the arterial wall for the peripheral vasculature aneurisms, a finite element modeling (FEM) is developed for analyzing the effects of arterial blood pressure and the arterial wall thickness in the aneurismal sac. The von Misses stresses, the transversal tensor stresses and the displacement in the aneurismal sac wall are analyzed. The possible site of rupture for this aneurism geometry is found surrounding the efferent artery and opposed to the flow inlet. A method for applying FEM to any aneurism geometry and blood pressure conditions is proposed for analyzing the risk of rupture and possible rupture site.
