ABSTRACT: The human body has been the subject of thorough researches—not only from medical perspective but from a technical one as well—are very rich, amongst them we find blood circulation system comprising: the heart, the arteries and the veins. The overriding role of these researches is to explain some cardiovascular pathology and provide an aid tool for the endoprothesis positioning in blood vessels while treating them. In this study we have developed a digital pattern using the common (engineering technique of the) finite element method (FEM) to simulate the mechanical behavior of the thoracic aorta and the abdominal aorta below the kidney under blood pressure effect. This pattern calculates the displacements, the stresses (constraints) and the deformations of the two arteries’ walls enabling us to know their experimentally determined mechanical and geometric properties. This pattern could be applied to detect the aneurysm and dissection phenomena.
