| Summary: | Filled rubber material is widely used in engineering vibration isolation structures. Accurately describing its hyperelastic properties is very important for accurate prediction of service performance of the engineering structures. Three basic mechanical tests including the uniaxial tensile (UT) , uniaxial compression (UC) and simple shear (SS) test were performed on an isolation rubber to character its hyperelastic mechanical behavior. Abilities of four commonly used hyperelastic constitutive models in predicting other kinds of deformations were discussed with incomplete data of these three basic mechanical tests. Three error evaluation indexes and a fitting goodness coefficient R were proposed to evaluate the fitting accuracy of each constitutive model. Finally, the applicability of different constitutive models under different experimental conditions was discussed and corresponding suggestions were given. |
