| Abstract: | A strain energy function, being split into isochoric and volumetric parts, was proposed for porous silicone rubber with relatively high porosity at finite deformation under compression. It turned out from the function that a constitutive relation for porous silicone rubber was derived. Comparison of theoretical prediction with experimental data was then carried out. The effect of porosity and volumetric deformation on compression behaviors of porous silicone rubber was discussed. |
