An axisymmetric solid SPH solver with consistent treatment of particles close to the symmetry axis

Résumé

A meshless Smoothed Particle Hydrodynamics solid solver is developed in order to study fluid-structure interactions and to predict cavitation erosion. The solid solver is developed in-house in an axisymmetric configuration. The existing SPH methods dedicated to solid materials do not allow a consistent treatment of particles close to the symmetry axis, so a density correction scheme is proposed here to derive new density and momentum equations for solid mechanics in axisymmetric SPH formulation. The new SPH equations are coded in the solver and the SPH solid solver is then validated against FEM results which shows excellent agreement.
