Cell wall mechanical properties of closed-cell Al foam
I Jeon, K Katou, T Sonoda, T Asahina, KJ Kang - Mechanics of Materials, 2009 - Elsevier
The mechanical properties of the cell wall, such as the elastic modulus, 0.2% offset yield
stress and power-law hardening exponent of the closed-cell Al foam are determined using
both experimental measurements and finite element analyses. A 6× 6× 12cm3 ingot of the
cell wall base material, which is sampled from melted Al-1.5 wt.% Ca alloy before foaming, is
prepared, and its mechanical properties are initially measured to set the limit values of the
mechanical properties of the Al cell wall. Two 5× 5× 5mm3 Al foam specimens of completely …
