Rubber-like hyperelastic materials are widely used in many engineering fields. In order to correctly assess the behaviors of rubber-made structures, constitutive models of materials are critical. According to International Standard ISO 37:2005, tensile experiments were done using M350-10kN-type apparatus. And then the Mooney-Rivlin parameters using experiment data are obtained under two different deformation. The results show that experimental process was quite reliable. It could provide the credible parameters of Mooney-Rivlin model to the further use the results in numerical analyses of rubber-made structures.
