Abstract

This paper describes a numerical method for elastic-plastic deformation of structure caused by impact pressure. Both fluid and solid phases are represented by SPH (Smoothed Particle Hydrodynamics), which is a typical particle method. We employed the artificial stress and coefficient of collapsing parameter, and also proposed the fluid structure interaction model in the original SPH. Our numerical results are in good agreement with the experimental data and the previous numerical results. Especially, we also compared the internal strain field with the numerical results. Furthermore, we also applied to some practical problems, such as collapsing of a concrete wall and steel flame structure.
