Finite element analysis of silicone rubber based on Yeoh constitutive model and Ogden constitutive model

Abstract

Based on the two constitutive models of Yeoh constitutive model and Ogden constitutive model, a finite element model of uniaxial compression experiment of silicone rubber was established. The stress-strain curves and stress clouds of different models of silicone rubber were compared to further verify the two models. It is found that the Ogden model (N=3, N=5) has a good fit between the stress-strain curve simulation results and the nominal stress-strain curve when there is only uniaxial compression test, and the model constant Compare solutions.
