The fluid-structure interaction simulation of shockand detonation-loaded thin-walled structures requires numerical methods that can cope with large deformations as well as local topology changes. We present a robust level-set-based approach that integrates a Lagrangian thin-shell finite element solver with fracture and fragmentation capabilities and an Eulerian Cartesian fluid solver with optio...

Technically relevant fluid-structure interaction simulation of detonation-induced dynamic response of thin-walled solid structures requires an efficient detonation solver that can cope with large deformations as well as arbitrary topology changes of the computational domain. We present a parallel adaptive method that uses a scalar level set function to represent embedded evolving solid boundari...

The fluid-structure interaction simulation of detonationand shock-waveloaded fracturing thin-walled structures requires numerical methods that can cope with large deformations as well as topology changes. We present a robust level-set-based approach that integrates a Lagrangian thin shell finite element solver with fracture and fragmentation capabilities with an Eulerian Cartesian detonation so...

We propose a two-fold approach to model reduction of fluid-structure interaction. The state equations for the fluid are solved with reduced basis methods. These are model reduction methods for parametric partial differential equations using well-chosen snapshot solutions in order to build a set of global basis functions. The other reduction is in terms of the geometric complexity of the moving ...

Background: The interaction between the blood and the vessel wall is of great clinical interest in studying cardiovascular diseases, the major causes of death in developed countries.Objective: To understand the effects of incorporating fluid-structure interaction into the simulation of blood flow through an anatomically realistic model of abdominal aorta and renal arteries reconstructed from CT...

This paper is concerned with the development of a fully implicit and purely Eulerian fluid-structure interaction method tailored for the modeling of the large deformations of elastic membranes in a surrounding Newtonian fluid. We consider a simplified model for the mechanical properties of the membrane, in which the surface strain energy depends on the membrane stretching. The fully Eulerian de...

In fluid-structure interaction problems, the computational domain is divided into a fluid and a structure part. The points in which both subdomains intersect, is called the interface. Forces are coupled through the interface. Therefore, an exact representation of the interface is of great importance. In this talk, we present an approach which assures the representation of the interface with hig...
