Structural Integrity Analysis and Experiment of Motor Grain under Low Temperature Ignition

In order to evaluate the security coefficient of certain solid rocket motor (SRM) grain under low temperature ignition, the simulation and test of SRM grain structural integrity are carried out. Based on the three-dimensional linear viscoelastic model, the structural integrity of the SRM grain under...
