摘要
Abstract
The relaxation modulus of the composite solid propellant expressed by Prony series were studied by traditional way,Joonas way and the way based on Prony series respectively. With the results and the linear viscoelastic theroy,the stress-strain response at the relaxation experiments and the constant rate of extension test of the speci-ment was obtained, then was compared with the experimental results. The results show that the relaxation modulus obtained by traditional way is less than the experimental result because of ignoring the strain loading stage. The relaxation modulus obtained by Joonas way is relatively more complicated because of having to calculate the change rate of stress. However, the relaxation modulus obtained by the way based on Prony series is not only with higher precision but also more convenient in data processing,and is a good way to calculate the relaxation modulus of composite solid propellant by the way based on Prony series.关键词
