Towards the theoretical development of the control of the action of the explosion of an overhead charge

Abstract

When a charge explodes on any solid deformable medium for the purpose of compaction, formation of depressions or destruction, intuitively care is taken to ensure significant amounts of vertical displacements or particle displacement velocities in the corresponding areas of the surface. Maximum displacements (or velocities) are expected in those areas of the boundary surface where the greatest compressive normal stresses are created. Tangential stresses during the free explosion of a charge on a surface are considered significantly less than normal, and they are often neglected. Horizontal displacements are also neglected, which naturally decrease away from the point of explosion according to the principle of radiation, and at the point of explosion, with symmetry, they should be zero.
