Characterization of initiation and detonation by Lagrange gage technology. [TATB and PBX-9404]
Experimental and theoretical studies on the Lagrange gage and analysis techniques for determining constitutive relationships and energy release rates in shocked explosives were performed. The experimental effort supported the Lawrence Livermore Laboratory (LLL) program to develop Lagrange gage technology for measuring Lagrange histories in shocked reacting explosives. In the LLL program, a stress gage package was developed for the explosive environment, preliminary sets of Lagrange pressure histories were recorded in shocked PBX-9404 and TATB, and particle velocity histories were recorded in shocked PBX-9404. In the theoretical effort the similarity solution, based on the initiation of PBX-9404, was examined to gain insight into the hydrodynamics of shock initiation in condensed explosives. Propositions were formulated for deducing hydrodynamic flow properties for a series of Lagrange pressure and particle velocity histories exhibiting maxima. These propositions were used to establish the phenomenology of the shock initiation process in PBX-9404 from the experimental pressure histories recorded at LLL. A Lagrange analysis was performed with the model solution to formulate and test methods for handling Lagrange gage records with pressure and particle velocity peaks similar to those exhibited by PBX-9404.
