Compressive deformation and energy absorbing characteristic of foamed aluminum

摘要: Experiments were carried out to investigate the deformation and energy absorbing characteristics mechanisms of foamed aluminum (FA) with two different matrices. Some new results obtained. It is found that, like other cellular solid materials, FA has a stress-strain curve three distinct regions, i.e., linear elasticity region, plastic collapse region or brittle crushing densification region. The capacity increases by increasing relative density yielding strength. Brittle foam exhibits higher than similar strengths. reaches its peak value efficiency at strain about 0.15 0.35, depending on density. AlMg10 shows Al foam.
