Notes:
In this study, the elastic buckling strength of cubic open-cell foams subjected to uniaxialcompression is investigated using the homogenization framework developed by the present authors(Ohno et al., JMPS 2002; Okumura et al., JMPS 2004). First of all, based on the framework, themicroscopic bifurcation and macroscopic instability of cubic open-cell foams are numericallyanalyzed by performing finite element analysis. It is thus shown that long wavelength buckling is theprimary mode and occurs just after the onset of macroscopic instability. Then, a solution forpredicting the stress of long wavelength buckling is analytically derived from the onset condition ofmacroscopic instability. The validity of this analytical solution is demonstrated by the finite elementresults
