| Abstract: | The stress distribution of solid rocket motor case at high pressure was analyzed and calculated by using the two-dimension axial-symmetric model and the finite element method. The plastic deformation and stress-field distribution of the motor case at work condition were obtained. The result can be employed in motor case assessment and reliability design based on plastic deformation. |
