Abstract
Porous aluminum is expected to be applied as a multifunctional material in various industrial fields because of its lightweight and high energy absorptivity. It is expected that, if the compression properties of porous aluminum can be estimated by analytical method, the practical use of porous aluminum is promoted in industrial fields. In this study, based on X-ray CT images of porous aluminum (ALPORAS), finite element modeling using voxel elements or tetrahedral elements was carried out. For each model, elastic finite element analyses were carried out under uniaxial compression loading. On the basis of analytical results, the effects of meshing on the stress concentration and stress distribution etc. were studied. Moreover, the possibility of evaluating the compression properties of porous aluminum was discussed.
