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%.
