dc.description.abstractSolid mechanics plays an important role in the progression and rupture of cerebral aneurysms. The hypothesis is that the mechanism that control aneurysm enlargement is the wall remodeling under the effect of time dependent arterial pressure. The mechanism of rupture could be based on plastic deformation under a fatigue-like mechanism. The current work describes the solid dynamics in 30 patient-specific models of cerebral aneurysms. An area based index shows significant difference between unruptured and ruptured aneurysms. The effective wall stress showed large variation depending on aneurysm size and form. A correlation between the maximal effective stress with the geometrical index was found.
