| Abstract: |
| Numerical simulation based on Abaqus and Matlab data processing tools,using data from uniaxial extension tests has been carried out to study the accuracy of Yeoh constitutive model,Ogden constitutive models and the pseudo-elastic model for characterising carbon-reinforced natural rubber's Mullins effect.The results show that:(1) When fitting the primary loading path,the curve of Ogden constitutive model has a higher accuracy than that of Yeoh constitutive model.And as carbon content increases,the precision of Yeoh model decreases in initial deformation region;(2) Relationship between pseudo-elastic parameters and the stretch has been determined,that is to say,a method of good precision and efficiency to calculate pseudo-elastic parameters by stretches is proposed. |
