| Research Abstract |
A new numerical simulation method which is applicable to large-scale and complicated fluid-structure interaction problem with free surface and large deformation has been presented in this research work. In order to treat the geometry of boundary, boundary condition and continuity condition at the boundary of fluid and structure, a finite cover method using Eulerian description based on fixed unstructured grid has been developed. The multi-scale method has been introduced to solve dynamic behavior of composite materials.
