RESUMO
The aim of this work is to investigate numerically and experimentally the mechanics of aortic aneurisms. The experimental part was performed at the Laboratory of Membranes and Biomembranes using silicone tubes with the geometry of the aorta under hydrostatic pressure. We investigate the behavior of the material tested and the critical pressure, this is the pressure necessary for the formation of aneurysms. The numerical analysis is done using the finite element code ABAQUS (6.8.1), and is validated by the experimental analysis. Some studies of geometrical and physical imperfections are performed, as well as the ones with constitutive equations for the material of the aorta.
