NUMERICAL METHOD OF HYDRO-ELASTIC PROBLEMS BY SPH AND ITS APPLICATION TO WAVE IMPACT PROBLEMS

Abstract

A numerical method for hydro-elastic problems was proposed in the present paper. In the method, both fluid and solid phases were described by SPH. We employed the artificial stress proposed by Monaghan (2000) to remove a tensile instability. We also applied to hydro-elastic problems caused by impact pressure due to free surface motion. The present numerical results were in good agreement with experimental results in elastic deformation and stress field. The numerical model also showed the possibility to compute dynamic response and vibration due to wave impact acting on elastic-vertical wall with several material properties.
