The vessel wall mechanics is described in regime of finite deformations by non linear hyperelastic structural models.
The research is focused on the mathematical and numerical modeling of the arterial wall and celebral aneurysms wall mechanics using hyperelastic materials to describe the biological tissue.
Another research topic is the computation of deflated vascular geometries starting from patient-specific vascular geometries reconstructed from radiological images, in order to simulate the prestressed state of arteries. This allow to obtain the initial reference configuration in view of fluid-structure interaction simulations.
