Abstract : In 1983, three spherical buried high explosive charges were fired to obtain dynamic material properties for in situ dry alluvium. This report contains a concise summary describing the test series objectives, rationale for gaging and placement, overall analysis, and recommendations for future tests. The key question concerning the design was what type of test should be fielded to give the most information about material properties used in calculating nuclear surface bursts. Particular requirements for measurement validation and redundancy of data were also key factors in the design. Several alternate approaches to data analysis by the various participants yielded results that pointed out the ability to determine uniaxially loading parameters of the material; however, stress difference and unloading estimates are still elusive. Important results, described in some detail, are the estimation of the dynamic loading uniaxial strain versus stress relationship, approach to development of a material properties test, analysis of stress gage performance, and recommendations for future material properties testing. Keywords: Ground shock, Shock wave propagation, Spherical shock wave, Contained burst, Nuclear explosion simulation.
