| Abstract: | The typical results are given for the master curve of the elongation of HTPB propellant. A twomodulus model for describing the tensile deformation and a tough fracture model for describing the tensile failure are suggested. Based on the models a theoretic method is induced to analysis and adjust the master curve of the elongation of HTPB propellants. |
