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. (© 2008 WILEY‐VCH Verlag GmbH & Co.
