NUMERICAL SIMULATION OF THE EXPLOSION INITIATION IN AP-PLEXIGLAS MIXTURE BY IMPACT

摘要

The theory for impact initiation of solid explosive mixture oxidizer-fuel mode is developed. Mathematical model is based on related equations for impact mechanics, viscoplastic-ity of thin layer of the material under study, kinetics of chemical reaction between oxidizer and fuel. Numerical simulation of the explosion initiation is carried out for ammonium per-chloratc ― polymctylmctacrylatc mixture. A good correlation between theoretical and cx-pcrimcntal results on impact sensitiveness this mixture is found. This work was supported by RFFI (Grant N 01-03-32053).
