| A mechanical characterization of closed-cell aluminium foams (AlSi12Mg0.6) prepared by powder metallurgy route under quasi-static and dynamic compressive loading was investigated. Cellular structure of some samples was evaluated using computer image analysis prior compression tests. The experimental tests were carried out on half-cylindrical specimens with surface skin in the density range of 350–550 kg/m3 (Note: one half of cylindrical specimen was used for quasi-static tests and other one for dynamic tests, thus having almost identical structure). The compression tests were performed with crosshead speed of 1.67.10-4 m/s for quasi-static and 3.72 m/s for dynamic tests. Based on the experimental data, a linear correlation between quasi-static and dynamic compressive strength at 20% and 50% strain is proposed. Obvious connection between strain rate, some properties of stress-strain curve and microstructure was observed. |
