Abstract
This study provides dynamic analysis of fluid-elastic solids using MPS (Moving Particle Semi-implicit) method. A twodimensionalcode based on particle interaction model of MPS method is developed to simulate fluid-structure interaction.The government equations of elastic structures are characterized by material density, Young's modulus and Poisson'sratio in solids. Meshes are not needed in the MPS method, so that fracture as well as large deformation can be analyzedwithout mesh distortion. The applicability of the present model is demonstrated for dam breaking. The result is in goodagreement with experimental data. Furthermore, structure analysis in a breakwater is carried out with wave propagation.The results rose the possibility that the present model can simulate fluid-structures interaction.
