Abstract:

This research is designed to improved the analysis and interpretation of shock-wave data in the hydrodynamic region gathered in the past or in the future to monitor agreed limitations on underground nuclear testing. Research accomplishments include 1 refinement and comparison to numerical simulations and actual nuclear test data of an approximate analytical model of the shock- front radius vs. time relationship for a variety of geological media 2 assembly of a Hugoniot database for several important classes of geologic materials 3 investigation--by means of the approximate analytical model--of the nature and physical basis of the insensitive interval discovered empirically in hydrodynamic data taken at US test sites 4 a rigorous analysis of the conditions under which cube-root scaling is an exact condition in the hydrodynamic region 5 detailed analysis using state-of-the-art, one- dimensional hydrodynamic numerical simulations of the effects of source parameters on hydrodynamic yield estimation 6 the development of a state-of- the-art, two-dimensional hydrodynamic code suitable for simulating two- dimensional source andor ambient medium effects.
