ANEOS (analytic equation of state package) models for shock compression of saturated limestone: Applications to ground shock calculations

Brown, W.T.

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 are compared with experimental and theoretical Hugoniots for saturated limestone samples with various porosity levels. Ground shock calculations are also performed to model a deeply buried 500 kiloton explosion in saturated limestone containing various amounts of water. 37 refs., 29 figs.
