The equation of state For expansion of detonation gas together with a model
for gas flow through fracturing solid is proposed and implemented into the
combined finite-discrete element code. The equation of state proposed enab
les gas pressure to be obtained in a closed form for both reversible and ir
reversible adiabatic expansion, while the gas Row model proposed considers
only 1D compressible flow through cracks, hence avoiding full 2D or 3D gas
flow through the fracturing solid. When coupled with finite-discrete elemen
t algorithms for solid fracture and fragmentation, the model proposed enabl
es gas pressure to be predicted and energy balance to be preserved. Copyrig
