Abstract

The shocking-to-detonation transition (SDT) of insensitive high explosives (IHE) including LX-17 and ultrafine TATB was studied by using Hybrid reaction rate model and modified JWL equation of state (EOS), and phenomena of colliding diverging detonation was numerically simulated. The calculated shocking-to-detonation transition (SDT) of insensitive high explosives is in agreement with the experimental result, and the calculated peak pressure in colliding diverging detonation increases 10%.
