In order to characterize uniaxial mechanical properties of modified double base propellant, a one dimensional form of viscoelastic-viscoplastic constitutive model is derived. In order to solve the first-order ordinary differential equations (ODEs) consisted by viscoplastic flow rule and internal state variables evolution, the backward difference formulas (BDF) is applied and achieved by MATLAB procedure.The effect of viscoplastic parameters on viscoplastic creep strain is analyzed by adjusting viscoplastic parameters based on a set of the given parameters, the results show that the greater values of viscoplastic potential energy parameter correspond to more flow while correspond to more flow,the greater values of the hardening function parameters result in less flow.
