On the theoretical development of controlling the action of a surface charge explosion
Abstract
When a charge is exploded on a solid deformable medium with the aim of compaction, the formation of depressions or destruction, care is intuitively taken to ensure significant values 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. Shear stresses during free explosion of a charge on a surface are considered significantly less than normal ones, 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, under symmetry, should be zero.
