This study aims to investigate the mechanical behavior of the ALPORAS closed-cell aluminum foam to compression, by means of experimental works as well as numerical simulations. To this end, a series of experiments are first conducted systematically. Effects of each of the testing conditions such as the specimen relative densities and the loading directions etc are accessed accordingly. In addition, observations made on the foam microstructure from our previous efforts are incorporated in the explanation of the present experimental results. On the other hand, a simplified yet representative 2-D numerical model based on a hexagonal geometry has been constructed. The model is subsequently adopted in predicting the foam elastic properties. The numerical results are lower than experimental results indicating such a simplified 2-D is not suitable for simulating the foam material studied that has complex 3-D microstucture.
