An adaptive level set method for shock-driven fluid-structure interaction

Abstract

The fluid-structure interaction simulation of shock- and detonation-loaded structures requires numerical methods that can cope with large deformations as well as local topology changes. A robust, level-set-based shock-capturing fluid solver is described that allows coupling to any solid mechanics solver. As computational example, the elastic response of a thin steel panel, modeled with both shell and beam theory, to a shock wave in air is considered.
