Head-on collision of normal shock waves with rubber-supported wall.

A physical model for describing the head-on collision process between a normal shock wave and a rubber-supported plate was developed. This model was solved numerically for three different modes of rubber loading; (1) uni-axial stress, (2) bi-axial stress, (3) uni-axial strain. The numerical solution provides information regarding the gas flow and the rubber properties at different times and location. The numerical results were compared with shock tube experiments. A good agreement was found between the numerical predictions and the experimental findings.
