A compression behavior of polymer foam was analyzed by using horaogemzation FEM code. A unit cell for the homogenization method was applied to a part of the microstructure. The polymer matrix of the unit cell was modeled hyperelasticity to consider non-linear characteristics. An original simulation model of the polymer foam was assumed to have two sizes of cells. (Cell is an air bubble in foam material.) Position of cells was assumed to be alternately and periodically. The diameter of cells was adjusted to make the density of the simulation model and the density of polymer foam coincident. The applicability of the analysis method to polymer foam was shown by comparison between the analysis results and the compression test results.
