Abstract : To study the cratering phenomena in a two-layered medium, a total of 32 model tests were performed. In all these tests the compressible stratum was simulated by dense sand while the stiff stratum was simulated by an artificial sandstone (cemented dense sand). Three different test techniques were used. Tests of Series I were performed with spherical explosive charges in half-space models consisting of colored thin substrata of sand and sandstone. Tests of Series II were performed using hemispherical explosive charges in quarter-space models behind a transparent Plexiglas wall. Tests of Series III were basically similar to those of Series I; they were also performed with spherical charges in half-space models.
