Movement of Variable-Density Inclusions in Wet Sand under Blast Loading.

The purpose of the study was to determine, for the cases of laboratory one-dimensional plane wave loading of a wet sand specimen and the combined airblast and ground-shock loading that occurs in wet sandfilled test pits in an HE field test, the effect of inclusion mass variation on their residual movements, and to infer from these determinations the effect of relative density, position of free-water surface, and surface membrane on the potential for liquefaction of wet sand under blast loading.
