The damage evolution of composite solid propellants is influenced by the stress state. In order to investigate the in-situ damage evolution mechanism of hydroxyl terminated polybutadiene (HTPB) propellant under tensile shear conditions, computer tomography (CT) technology was used to scan and recons...
