The objective of this paper is to study the mechanical behavior of the abdominal aortic aneurysm (AAA) created from the xenograft rat model. Based on uniaxial traction tests on arterial samples on the one hand, and histological analysis on the other, a finite element model is proposed. By considering the mechanical behavior of the AAA tissue as hyperelastic, isotropic and incompressible, the wall stresses are calculated. We show that the peak stress is localized where the thrombus created by the xenograft rat model is thinner.
