Constitutive modeling of weak and strong shock-initiation of porous explosives
Conference
·
OSTI ID:350875
A continuum based reactive burn model for shocked loaded high explosives has been developed that uses heterogeneous distribution of pore collapse energy to one or more of the constituents (a hot spot) as an ignition source, represents constituents with independent equations of state and has multiple competing and sequential chemical reactions. Reaction propagates from the hot spot to the remainder of the material through either a pressure or temperature dependence of heat transfer through a film layer. The reaction may be quenched by heat transfer or shock release if it is not rapid enough.
