Mechanical damage and aging are the main mechanisms of nonlinear characteristics of solid propellant.A comprehensive big strain visco-elastic constitutive model with damage mechanics and aging was established, by using the visco-elastic constitutive equations form expressed by the generalized variable, introducing damage variables, and taking the relaxation modules after aging to characterize the aging. The correctness of the model was verified through experiments. the parameters need by modeling are easy to be got, and converted into the finite element code to do the simulation computation, then the model is suitable for the engineering application.
