Paper Abstract

Recently, the behavior of explosive materials under intermediate loading rates (100 - 104 s-1) has become of interest. Shock and quasi-static behaviors have been well characterized, but in weapons such as a deep earth penetrator, loading conditions in intermediate strain ranges will occur previous to initiation and affect the response of the explosive. Impact tests of the explosives Tritonal and PBX-N109 were conducted at the Advanced Warhead Experimentation Facility at Eglin AFB, FL. The tests show that these materials fragment under dynamic shear loading and require high hydrostatic loads after failure to generate internal friction needed for initiation. Macroscopic, adiabatic shear localization is not a feasible initiation mechanism for these materials under these loading conditions.
