Explosively driven fragmentation mechanisms of Al-W particulate composite rings were investigated. The effect of mesostructure (particulate Al and W, particulate Al and W fibers) and bonding between Al particles (processing via cold isostatic and cold isostatic + hot isostatic pressing) were determined. The kinematics of the expansion process was monitored using Photon Doppler Velocimetry measurements of the velocity of the outer surface of the rings. Numerical simulations of the expansion velocity of rings were in agreement with experimental data. The agglomerated fragments larger than sizes of initial Al particles were observed in

“…The reason should be that the equation of state does not always completely reflect the actual situation of the aluminum particles reaction in the detonation of the aluminized explosives. Ripley et al [13] added the crushing model of aluminum powder to the detonation process and calculated the shock wave pressure of the explosion of aluminized explosives in air. The calculated results are basically in agreement with the experimental results.…”

In order to explain the detonation performance of RDX‐based aluminized explosives with different aluminum particle sizes, a new equation of state (EOS) for aluminized explosives is proposed. The proposed EOS regards the gasification of aluminum particles as a real reaction. The proposed EOS takes account of constituent aluminum particle sizes. The proposed EOS was implemented in LS‐DYNA as a user defined EOS and validated by simulating the experiments of metal plates acceleration caused by detonation of RDX‐based aluminized explosives. The numerical results reproduce the experimental finding that the reaction rate of aluminum particles increases with the decrease of aluminum particle size. The proposed EOS has several advantages over the previously reported equations of state for aluminized explosives. The reaction rate of aluminum constituents is calculated theoretically from their gasification reaction rate equation eliminating the need for experimental calibration of the corresponding empirical parameters.
