Abstract:

GEOLOGIC MATERIAL PROPERTY REQUIREMENTS FOR NUMERICAL CALCULATION OF AN EXPLOSIVE EVENT DEPEND ON SEVERAL FACTORS, INCLUDING: THE PEAK PRESSURE EXPECTED OR ACHIEVED, THE GEOMETRY OF LOADING, AND THE TYPE OF CALCULATION BEING PERFORMED. ADDITIONALLY, THE CLASS OF GEOLOGIC MATERIAL INVOLVED; E.G., SAND VERSUS CLAY VERSUS ROCK, WILL DICTATE REQUIREMENTS BASED ON WHAT ARE ANTICIPATED TO BE THE IMPORTANT BEHAVIORAL PHENOMENA. CURRENT AIR FORCE REQUIREMENTS CALL FOR ACCURATE IN SITU PROPERTIES IN THE 1-10 KILOBAR PRESSURE REGION FOR SURFACE BURST LOADING IN SEVERAL DIFFERENT GEOLOGIES. THE PROPOSED EFFORT WILL INVESTIGATE HOW THE CYLINDRICAL IN SITU TEST (CIST) TECHNIQUE, CURRENTLY USED FOR OBTAINING PROPERTIES AT LESS THAN ONE-HALF KILOBAR, MAY BE EXTENDED TO HIGHER PRESSURES. THE PROPOSED METHODOLOGY IS DESCRIBED AND CALCULATED STRESSES AND MOTIONS ARE SHOWN FOR A DRY ALLUVIAL GEOLOGY. FIELDING AND INSTRUMENTATION REQUIREMENTS ARE DISCUSSED AND COMPARED WITH OTHER EXPLOSIVE IN SITU PROPERTY TEST GEOMETRIES.
