The aim of this study is proper description of stress-strain behaviour of the metal foam structure Alporas under high-strain rate loading. Stress strain curve of Alporas specimens is measured during an impact test using a drop tower device. Strain of the specimens is evaluated by two independent approaches: i) double numerical integration of acceleration data and ii) digital image correlation technique. Resulting stress-strain curves are compared with behaviour of polystyrene material samples and results obtained from quasi-static compression testing.
