Products: Abaqus/Explicit Abaqus/CAE
Benefits: The ignition-and-growth equation of state is now available in Abaqus/Explicit. It can be used to model the shock initiation and the detonation wave propagation of high-energy solid explosives.
Description: The ignition-and-growth model is a phenomenological model, in which the heterogeneous explosive is modeled as a homogeneous mixture of two phases: the unreacted solid explosive and the reacted gas products. Separate JWL equations of state are prescribed for each phase, and a single reaction-rate law is prescribed for the conversion of the explosive to products.
