Abstract

Abstract: The results of two sets of cylinder test for aluminized explosive to study the dimension effect of accelerating ability and Jones-Wilkins-Lee (JWL) equation of state for aluminized explosive were reported, with diameter of 25 mm and 50 mm, respectively. By using theory analysis and 2D numerical simulations for the cylinder test, the parameters of JWL equation of state for aluminized explosive were determined. The result indicates that the big aluminized explosive charge has higher ability of accelerating than that of the small one, and its parameters of JWL equation of state are different from small ones.

Key words: mechanics of explosion, aluminized explosive, accelerating ability, Jones-Wilkins-Lee equation of state, dimension effect, cylinder test
