提出了一种二维SPH-FEM模型，研究其在流固耦合问题中的应用。流体模型基于光滑颗粒流体力学理论，结构动力学采用大变形有限元法。本文介绍了SPH模型和FEM模型的基本原理，并介绍了松散耦合SPH - FEM模型的发展。给出了两个基准FSI问题的验证结果。第一个测试案例是与弹性体相互作用的晃动水池中的流动（Souto-Iglesias et al., 2008），第二个测试案例是通过弹性闸门的溃坝流（Antoci et al., 2007）。SPH-FEM模型的计算结果与已有的实验结果吻合较好，表明SPH-FEM模型是求解FSI问题的一种可行、有效的数值工具。
A two-dimensional SPH–FEM model is proposed to investigate its application in the fluid–structure interaction (FSI) problem. The fluid model is based on the theory of Smoothed Particle Hydrodynamics (SPH) and the structural dynamics employ a large-deformation Finite Element Method (FEM). This paper describes the basics of both SPH and FEM models and presents the development of a loosely coupled SPH–FEM model. Validation results of two benchmark FSI problems are illustrated. The first test case is flow in a sloshing tank interacting with an elastic body (Souto-Iglesias et al., 2008) and the second one is dam-break flow through an elastic gate (Antoci et al., 2007). The results obtained with the SPH–FEM model show good agreement with published experimental results and suggest that the SPH–FEM model is a viable and effective numerical tool for FSI problems.
