Ground Shock Calculation Parameter Study
The report is the third in a series, 'Ground Shock Calculation Parameter Study, ' centered on the Prairie Flat Event. The first report describes the effect of different elastic-ideally plastic constitutive model formulations on calculated ground shock, while the second report describes the effect of different bottom boundary conditions. The report documents the results of a parameter study conducted to determine the effects of using different types of nonlinear constitutive models to fit a given set of soil property data in calculations of high-explosive, airblast-induced, superseismic ground shock.

Free-field Code Predictions Versus Field Measurements
The report documents the results of an airblast-induced ground-shock calculation performed at the U.S. Army Engineer Waterways Experiment Station (WES) for the Operation Prairie Flat 500-ton high-explosive (HE) event. A WES-modified version of the 2D axisymmetric LAYER Code developed by the Paul Weidlinger firm was used for the investigation. Each layer of the soil profile was mathematically modeled with a nonlinear elastic-plastic-compacting type constitutive model that provided good fits to the available material property test data. Field airblast measurements were used to develop an airblast routine suitable for code input. The code results, carried to 300 msec of real time, showed good q...
