Abstract

This paper describes buckling modes and stresses of elastic Kelvin open-cell foams subjected to uniaxial compressions. Cubic unit cells and cell aggregates in model foams are analyzed using a homogenization theory. The analysis is performed on the assumption that the struts in foams have a non-uniform distribution of cross-sectional areas as observed experimentally. By performing the analysis based on the uniformity of strut cross-sectional areas, it is shown that the non-uniformity of cross-sectional areas is an important factor for the buckling behavior of open-cell foams.
