Abstract: A study of propellent aging,using inversion transfoimation from experimental relaxation functions to creep functions,is presented.The finite element method is intro-duced in the analysis.After having solved the aging problems of beams,the long term ag-ing effect of a solid propellent grain is also analyzed as an example.
Key words: propellent grain, viscoelasticity, relaxation function, creep function
