Abstract: Polyurethane foams are a kind of energy absorbing material,and its mechanical behavior can be modeled by endochronic theory. This paper introduces the endochronic theory into the constitutive models of polyurethane foams and model for the isothermal small strain is derived from Gibbs free energy. Based on these,instructional tendencies of the model are also discussed.

Key words: polyurethane foam, constitutive model, endochronic theory
