摘要
Abstract
A nonlinear viscoelastic constitutive equation with cumulative damage was proposed to model modified double base propellants.This model is based on Schapery's nonlinear viscoelastic constitutive equation with damage,and is composed of pseudo-strain and a nonlinear coefficient that is a function of a damage parameter.A method for determining the parameters was introduced, with the parameters obtained through relaxation and uniaxial constant strain rate tension tests.Predictions using the constitutive equa-tion are in good agreement with experimental measurements from constant strain rate tension tests and complex train history tension tests.关键词
