Effect of Mechanical Heterogeneity on the Structural Integrity of HTPB Propellant Grain

Effect of Mechanical Heterogeneity on the Structural Integrity of HTPB Propellant Grain

To investigate the structural effects of the mechanical heterogeneity of Hydroxyl-terminated polybutadiene (HTPB) propellant grain under ignition pressurization, a gradient finite element method was proposed to evaluate its structural integrity. The heterogeneous mechanical properties of the propell...
