Abstract
In this paper behavior of stress wave in a solid body induced by shock wave is discussed. Interaction between shock and solid sometimes causes serious problem such as the destruction of glass and structures by shock generated from supersonic plane, explosion and so on. In recent years, although the mechanism of interaction has been studied by many researchers, the details of process have not been known enough yet. In this study, the interaction phenomenon between shock wave emitted from diaphragmless shock tube and solid block made in acrylic or polycarbonate is visualized using Schlieren method. Motion of shock wave and its effect on block are examined by numerical simulation of the flow field using TVD scheme. As a result, it is found that stress wave is generated in block by the impingement of shock and its propagation speed depends on the material properties of block and the strength of shock.
