Based on the Modified Ghost Fluid Method (MGFM) and Modified Ghost Solid Method (MGSM), the Modified Ghost Method (MGM) is developed to deal with the combined compressible multi-fluid multi-solid interactions. The exact solution for 1D fluid-elastic-plastic solid Riemann problem is derived, which is subsequently used to verify the validity of the MGM as applied to fluid-elastic-plastic solid interaction. Using MGM, we construct a coherent and consistent approach to simulate truly compressible multi-medium problems as for gas-water-solid-solid interaction. Similar to the 1D cases, several 2D multi-medium cases are simulated to show the versatility and ease of application for the MGM. Finally, a multi-medium case with a complex geometry in solid domain is simulated, which shows that the proposed approach can be effectively used to study the response of the various structure domain.
