Abstract: | The interaction of underwater explosion waves with aluminum foam plates with different cell types is investigated. It is shown that the transmitted wave that passed through a closed-cell sample can be decomposed into two parts, one with a low-frequency content, which corresponds to the gas pressure in the pores, and one with a high-frequency content, which is argued to be a coupling of waves transmitted by the matrix and wave interactions between the fluid and the matrix of the medium. |
