Abstract
The defoThe deformation behaviors and energy absorption characteristics of constructed cellular aluminums were investigated by compressive tests. Constructed cellular aluminum specimens with two kinds of thickness in the cold-pressed panel and various numbers of layers bonded together have been tested. The plateau stress and the energy absorption have been measured and furthermore, the deformation behaviors have been evaluated. Results indicate that superior mechanical properties with constructed cellular aluminums can be achieved when the distribution of material at cell level is properly selected. Excellent energy absorption per unit mass can be obtained by only changing the thickness of the original aluminum sheet.nnation behaviors and energy absorption characteristics of constructed cellular aluminums were investigated by compressive tests.
