The present work suggests an experimental set-up for analyzing the shock transfer through porous materials such as sand. Within this set-up, the corresponding experiments observe the shock wave transmission through a porous material using flash X-ray images of the deformation of a circular thin metallic plate, where the plate is impacted by the sand ejecta due to the loading by a buried high explosive charge. The materials analyzed include calcite sand and several quartz-based sands. The loading is performed by two different charge configurations representing a variability in the loading input. The images demonstrate a good sensitivity of the suggested test set-up to the material variations, which enables one to employ the corresponding test results for model validation. The observations are used in the present work for validation of a two-phase constitutive material model implemented in the CTH hydrocode. The CTH modelling employing the two-phase model demonstrates that the model is suitable for describing the test results. |
