  Objective: Abdominal aortic aneurysms (AAAs) are characterized by structural remodelling resulting in the gradual weakening and expansion of the aortic wall. Wall stress may furnish a usable indicator to prevent the failure. In order to evaluate this risk, static pressure aging on the cap was used to perform FEA, simulating an aneurysm varying its dimensions from 10 mm to 50 mm. Analyses were carried out by imposing different thickness of the cap, and obtaining correspondent equivalent Von Mises stresses. Understanding how these stresses are distributed and what factors influence stress distributions is critical in evaluating the potential for rupture. Methods: A representative FE model was created in order to simulate the historical evolution of the AAA. CFD analyses were performed to obtain data of the static pressure aging on the model. Pat..
