Development of Higher-order Partitioned Schemes for Fluid-structure Interaction Problems with Large Displacement

Fluid-structure interaction (FSI) problems arise in many applications, such as hemodynamics, aerodynamics, and biomedical engineering. In applications to hemodynamics, FSI models have been used to describe the interaction between blood and vessel walls. This project focuses on the derivation and analysis of partitioned methods for FSI problems, where the structure is described using both elastic and poroelastic models. We used these models to better understand the role of a blood clot in the risk of rupture of abdominal aortic aneurysm. Our findings quantify the relation between the physical properties of the blood clot and the wall stress in the aneurysm.
