Scaled depth of burial formula
WebNov 23, 1998 · The results from the depth of burial experiment (DOB) are consistent with cube-root scaling and with previous observations that the source corner frequency for underground explosions increases with depth. The corner frequencies, however, were overpredicted by Mueller and Murphy (1971) and underpredicted by Denny and Johnson … WebJul 1, 2024 · Most scholars choose the main parameters: charge (W), depth (d), crater radius (R), the density of soil (ρ), and bulk modulus (K). By dimensional analysis, the density of soil (ρ) has been removed from the portfolio, which means that the cratering scale does not depend on the material inertia.
