| Abstract: |
| The uniaxial extension behaviour of vulcanized EPDM/polyamide(PA) blends was simulated with Rivlin model.The results showed that the Rivlin model with two parameters could be used to describe the stress-strain behaviour of statically vulcanized EPDM/PA blends with the addition level of PA up to 30 phr;the Rivlin models with three and five parameters gave good fit of statically vulcanized EPDM/PA blends with the addition level of PA used in the test;and the Rivlin model with three parameters could be used to describe the stress-strain behaviour of dynamically vulcanized EPDM/PA,but as the addition level of PA increased over a certain level,the dynamically vulcanized EPDM/PA blends would show the remarkable plastic characteristics and their fit curves would deviate from the test data. |
