Computational Study of Shock Propagation in Indiana Limestone.

摘要

Simple mixture rules are used to calculate input parameters for an analytic equation of state package (ANEOS) to model saturated limestone as a homogeneous material. This method is used to determine changes in material parameters as the volume fraction of water in the rock changes. Hugoniots determined from these calculations are compared with experimental and theoretical results for saturated limestone. Ground shock calculations are also performed to model a deeply buried explosion in saturated limestone containing various amounts of water. 11 refs., 4 figs.
