摘要

In this study, a transient finite element model, accompanied by the time-temperature shift principle, is used to simulate the transient response of a solid rocket motor so that the response of the propellant grains under real ignition pressurization loading conditions is investigated. The results show that the transient effect is important for structural completeness of the solid propellant grains under the ignition loading conditions. There is an apparent difference among the stresses of different Poisson's ratios. When changing the property of propellant grains from compressible into incompressible, the stress and strain of propellant grains under ignition pressurization loading decreased significantly. The stress variation versus Poisson's ratio is nonlinear and cannot be neglected.
