| Abstract: | For solid propellant, a creep damage evolution model coupled with temperature phase has been established. The creep fracture is tested under uniaxial and biaxial conditions lo determine propellant parameters. The model has an a practical value for stress analysis and life prediction of composite solid propellants. |
