Abstract
In this study, an evaluation method of foamed rubber considering the mechanical characteristics of rubber matrix and its microstructure was proposed. In order to develop the evaluation method, the microstructure of the foamed rubber is assumed to have periodic microstructure, and a FEM code for hyperelastic material was developed based on homogenization theory. Furthermore, compression test of the rubber specimen reproducing FEM model was conducted to verify the applicability of analysis code. Relative density was reproduced by adjusting the diameter of the pores. The analysis result showed good agreement with the compression test result in small strain region.
