The aim of this paper is to deep understand the pressurization behavior in evolution of crack burning, and promote the acknowledge level for transition mechanism of high intensity reaction in projectile fillings under accidental ignition. Based on qualitative analysis for pressure evolution in explosive crack burning, theoretical calculation is carried out for the pressurization process in crack burning of a HMX-based PBX (with a content of 95% for HMX). Simplified flow model for explosive burning products has been set up based on gas dynamic theory. With the hypothesis of one-dimensional isentropic flow, crack pressurization process has been predicted without regard to viscosity and friction resistance. The calculation result is qualitatively accord with experimental result in pressurization stage, providing a theoretical explanation for understanding the pressurization behavior in crack burning. © 2020, Editorial Staff of EXPLOSION AND SHOCK WAVES.
