Influence of the fluid-structure interaction in biomechanics: application to parametric modal analysis and dynamics of the aorta under a shock

Résumé

The ascending branch of the aorta is one of the most stressed organ of the arterial system. We aim to design a biomechanical model for analysing the aorta dynamics under a shock. The model includes the aorta layers and the influence of the blood pressure. First, we undertake a modal analysis of the coupled aorta-blood system. For the analytical solving we adopt the Helmholtz decomposition. The finite element model is then validated by these original analytical solutions. The second part focuses on aorta-blood dynamics, corresponding to an acceleration/deceleration during car crash. Numerical and analytical solutions are compared.
