| Abstract: | A three-phase viscoelastic constitutive model is proposed and verified for prediction of the mechanical properties of NEPE high energetic propellants.The relationships between mechanical properties of NEPE propellants and the formulation,particle size,gradation,modulus and tensile strength of matrix,etc.are constructed mathematically.The results show that the predictions of this model is in good agreement with experimental measurements for both tensile strength and elongation of NEPE high energetic propellants. |
