主　　题：Fluid-structure interaction(FSI) smoothed particle hydrodynamics(SPH) total Lagrangian formulation 

摘      要：This work concerns numerical modeling of fluid-structure interaction（FSI） problems in a uniform smoothed particle hydrodynamics（SPH） framework. It combines a transport-velocity SPH scheme, advancing fluid motions, with a total Lagrangian SPH formulation dealing with the structure deformations. Since both fluid and solid governing equations are solved in SPH framework, while coupling becomes straightforward, the momentum conservation of the FSI system is satisfied strictly. A well-known FSI benchmark test case has been performed to validate the modeling and to demonstrate its potential.
