Smoothed particle hydrodynamics modelling in continuum mechanics: fluid-structure interaction

Abstract

Within this study, the implementation of the smoothed particle hydrodynamics (SPH) method solving the complex problem of interaction between a quasi-incompressible fluid involving a free surface and an elastic structure is outlined. A brief description of the SPH model for both the quasi-incompressible fluid and the isotropic elastic solid is presented. The interaction between the fluid and the elastic structure is realised through the contact algorithm. The results of numerical computations are confronted with the experimental as well as computational data published in the literature.
