A concept for aortic dissection with fluid‐structure‐crack interaction

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

In aortic dissection, the layers composing the aorta rupture, allowing blood to enter the vessel wall. This process is modeled applying a monolithic fluid‐structure interaction framework, formulating the Navier‐Stokes equations for incompressible flows as well as the mixed finite strain elastodynamics equations in the Lagrangian frame of reference. Continuous test‐ and trial function spaces are employed in the whole domain, rendering the coupling straightforward. Within this contribution, a predefined function indicating failure is used to convert solid to fluid elements, thereby mimicing tissue rupture.
