| Abstract: |
| Combining the Neo-Hookean and Yeoh’s constitutive models of hyperelastic materials with the microstructures in foamed silicone rubber，the porosity of the silicone rubber was introduced to the strain energy density functions and constitutive equations as a parameter，and the prediction model for the mechanical properties of the foamed silicone rubber was established. The mechanical properties under uniaxial compression and simple shear were also investigated by using finite element method（FEM） and mechanical experiments, respectively. The results showed that the theoretic models based on the microstructure of foamed silicone rubber could well describe its mechanical response. Moreover, the effects of loading rate and environmental temperature on the mechanical properties of foamed silicone rubber were studied，which provided the guidance to its applications. |
