Abstract: To develop an engineering model based on the physical mechanism of the non-shock initiation reaction of structural
charge, which can be used to describe the reaction evolution process and quantify the reaction intensity for evaluating weapons
and ammunition safety. Considering the cavity expansion volume, a constrained charge combustion reaction evolution model
was established in this paper, with fracture toughness and reaction pressure as the main parameters based on the main control
mechanism of charge reaction crack propagation, which can describe the combustion gaseous product pressurization and shell
constraint strength during combustion evolution. Relevant details for the control model establishment process were given. The
model reliability of confined charge reaction combustion evolution was verified via the experiments of PBX-3 (87% HMX)
explosive combustion reaction evolution under mass inertial confinement. The mass velocity time was recorded by PDV
(photonic Doppler velocimetry) transducers, the pressure-time profiles were recorded via pressure transducers, and the
experimental process was captured via a high-speed camera. The experimental results were compared with calculated results
from the control model proposed in this work. The results show that the reaction pressurization process calculated via the
model is roughly consistent with the pressure-increasing trend in the experiment (calculated by the mass velocity). The control
model considering the structural venting effect can reflect the competition mechanism between combustion gas pressurization
