Open cell polyurethane foam is used in various products. Product design method of open cell foam by numerical analysis has not been established because the mechanical properties of the material are complicated. In this study, FEM analysis method is proposed to predict the mechanical properties of polyurethane foams considering the matrix and its microstructure. The polyurethane matrix were assumed to be approximated by the isotropic hyperelastic model. The Yeoh model was applied to the potential energy function of the hyperelastic model. The microstructures of two polyurethane foams were obtained by the CT-scanning system. FEM analysis models were prepared from the CT-scanning data. From simulated results, the influence of analysis area and the boundary condition were evaluated.
