Abstract
This paper presents stabilized finite cover based fluid-structure interaction analysis including fracture of structure. The fracture of structure and the contact of structure uses the discrete element method using Cohesive model. The stabilized method based on SUPG/PSPG methods are employed to solve the incompressible Navier-Stokes equation. Since the physical domain is defined independently of the mathematical domain in the finite cover method, the physical boundaries of the structure are represented explicitly in a spatially fixed mesh so that the continuity condition can be imposed directly on the actual interface within the framework of Eulerian approach, and the continuity conditions of velocity and stress vectors at the interface are imposed with the penalty method. Several numerical examples are presented to demonstrate the validity and efficiency of the proposed fluid-structure interaction method.
