Study on the Stress–Strain Relationships and Deterioration Modes of HTPB Propellant with Prefabricated Cracks

Penetrating cracks with different crack angles were prefabricated in viscoelastic hydroxyl-terminated polybutadiene propellant specimens. Microphotography was performed while tensile tests were conducted on a universal testing machine at tensile rates of 2 mm/min, 10 mm/min, and 500 mm/min. Specimen...
