Porous aluminum is a multifunctional material with both lightweight and high energy absorption properties. In this study, functionally graded (FG) porous aluminum was fabricated by spacer method varying pore structures. The obtained FG porous aluminum was observed non-destructively by X-ray CT. Image-based finite element analysis of FG porous aluminum using X-ray CT images was conducted. By comparing the results of finite element analysis and the deformation behavior of actual compressive tests of FG porous aluminum, it was shown that deformation behavior can be controlled by varying pore structures.
