【Abstract】 The Mooney-Rivlin model,which was common in FEA,was used to model the uniaxial extension behaviour of closed cell NR and NBR foams.The results showed that the extension behaviour of closed cell rubber foam calculated with the Mooney-Rivlin model was well fitted to that from the practical measurement;and the air in the foam cell featured entropical elasticity,uncompressibility and isotropy.更多还原
