摘要：

This paper describes the finite element implementation of a recently developed constitutive model for the chemical aging of rubber in deformed states. The model was developed from molecular dynamics simulations that investigated two stage networks. The model includes the effects of multiple stages of cross-linking and scission while the sample is deformed and the effects of physical entanglements. Given the deformation and chemical history of a sample, finite element calculations using this model are shown to make quantitative predictions of permanent set for two sample experimental systems.
