We present a new constitutive equation which enables to simulate experimental cyclic stress-strain responses in a carbon-black filled SBR rubber. The constitutive model for the basic elasticity is based on the Yeoh model, and the theory of finite viscoelasticity with an intermediate configuration is used to describe the rate dependent behavior. The simulated results were approximately consistent with the experimental ones; therefore, the proposed model reproduced the experimental cyclic stress-strain responses of the vulcanizates under wide ranges of applied strain and strain rates with satisfactory accuracy.
