“…In previous experimental works, it was already demonstrated that cell morphologies and structures play an important role in the initiation and propagation of the deformation behavior of the closed-cell aluminum foam [6,15,16,17,18]. These results indicated that the collapsed band always initiate from cells with their longest semi-axis perpendicular to the loading direction.…”

It is well-known that cell morphology plays a vital role in the mechanical properties of the closed-cell aluminum foam. In this work, a three-dimensional (3D) realistic structure was obtained by using the synchrotron X-ray micro-tomography technique and then translated into a numerical model for a further finite-element simulation. In order to investigate the early compressive deformation in the closed-cell aluminum foam, we chose three different strain levels, namely, 0.2% (initiation of plastic strain), 2.8% (propagation of plastic strain band), and 6% (formation of collapse band) to discuss the evolution forms of plastic strain concentration by simulation. We found that the curvature, anisotropy, and distribution of cell volume of adjacent cells played a vital role in the initiation of plastic strain. Furthermore, the phenomenon that plastic strain band propagated along the direction aligned 45° with respect to the orientation of the compression was also investigated in the propagation of the plastic strain band and formation of the collapse band. Finally, the comparison between experimental results and simulation results was performed to illustrate the early location of these three different levels in the whole compressive deformation.

Lightweight porous metals have been focused on as structural and energy absorbing materials. Mechanical properties of classical porous metals fall under the specific specimen dimension. Such cell size effects are mainly caused by the disordered cells. The present study experimentally evaluates the cell size effects of additively manufactured porous metals consisting of ordered cells. Different sized porous titanium specimens consisting of ordered rhombic dodecahedron cells are manufactured through electron beam melting process. Mechanical properties are determined by quasi-static compression tests. The plateau stress and the energy absorption are almost independent of the specimen dimension divided by the cell diameter. Experimental results conclude that the cell size effects are suppressed in additively manufactured porous metals consisting of well-defined ordered cells.
