Copyright © 2015 by The Minerals, Metals & Materials Society. All rights reserved.The mechanical response of closed-cell aluminium metallic foams subjected to low and high strain-rate loading has been investigated. A set of quasi-static and dynamic (shock) compressive tests have been conducted on closed-cell aluminium foams (CYMAT) with densities of 0.50 and 0.30 g/cc. Post-mortem characterization via optical microscopy and electron backscatter diffraction (EBSD) was performed on pristine and deformed specimens to elucidate the dominant deformation mechanisms in these materials. The combination of these techniques allowed for the assessment of critical deformation parameters such as changes in cell geometry and morphology, as well as microstructural evolution and deformation of the aluminium cellular network. These findings aim to aid in the design and development of optimized material structures for impact and blast protection.
