The Moving-Particle Semi-implicit (MPS) method is a type of meshless Lagrangian calculation technique that uses particles to perform calculations instead of meshes. This method is straightforward and has a high computational efficiency. In this paper, a Lagrangian model for the numerical simulation of fluid-structure interaction problems is proposed. In the proposed method, both the fluid and the structure are described by the MPS. The fluid is fully coupled with the solid that can undergo large structural deformations. In practical engineering, many existing fluid problems involve turbulent flows. The large eddy simulation (LES) method is a major means of studying turbulence. The modified MPS method with the LES method is applied in two-dimensional dam-break problems, which validates the use of the MPS method for solving fluid-structure coupled problems with turbulent flows. By taking the meshless advantage of the MPS method, a preliminary simulation of the plate break problem is carried out, and the simulation results are theoretically verified.
