Abstract

An experimental study was conducted in a vertical, 31×31 mm2 cross-section, shock tube. The investigation included measurements of the gas pressure and the compressive stress; based on the observed measurements the trajectories of the principal disturbances inside the granular layer were reconstructed. Results of this study show that two different effects, gas filtration and mechanical response of a granular layer to the weak shock wave loading, are of paramount importance and depend on the layer characteristics.
