Two kinds of cell models, include of Octahedron cell model and Tetrakaidecahedron cell model, were analyzed for the open-cell Aluminium foams. Simulation results show that the compression load-time curves of the two models have the same trend. There are three stages, elastic region, yield region, densification region. In addition, The Tetrakaidecahedron model calculation and predication show good agreement with the experimental results. Its simulation results of platform stress closer to the experimental value in the two models. Therefore, Tetrakaidecahedron model was the best choice to simulate the aluminium foams.
