Abstract

Abstract

A novel experimental technique to study the reaction threshold of explosives is developed. The flyer is accelerated to an expected velocity to gain a low amplitude loading by the gas gun. The interface particle velocity between JOB-9003 and PMMA under different stresses is measured with electromagnetic particle velocity gauges. The interface velocities of unreacting and reacting explosive are achieved based on the curve of the explosive interface particle velocity. The relationship ofu_p-p is achieved according to interface velocity of unreacting and reacting explosives. The chemical reaction threshold and the ignition threshold of JOB-9003 are 1.65 GPa and 2.62 GPa under the low amplitude loading.
