CALCULATION OF UNDERGROUND AND SURFACE EXPLOSIONS.
Abstract
A calculational program is described which has been directed toward prediction of shock strength and ground motion resulting from chemical or nuclear explosions contained in or on the surface of geologic materials. Two-dimensional time-dependent computer codes have been developed that can be applied in the high-pressure region near the explosive source where violent distortion develops, as well as in lower pressure regions where material strength is important. Equations of state have been used that take into account the irreversible compaction of porous materials and also the contribution of internal friction to shear strength. Calculations are reported of TNT explosions at the surface of limestone and buried in a layered soil. (Author)
