Research Abstract

Functionally graded (FG) aluminum foam containing A1050 pure aluminum and ADC12 aluminum alloy was fabricated. The FG foam has the potential for its location of deformation to be controlled. Moreover, a FG foam with plateau regions and stresses corresponding to those of the uniform A1050 and ADC12 foams was obtained. Also, we performed image-based finite element (FE) analyses of FG aluminum foam using X-ray computed tomography (CT) images and investigated the possibility of predicting its deformation behavior by comparing the results of FE analyses with those of actual compressive tests.
