On the effective elasticity tensor of cellular materials obtained by an energetic homogenization procedure

Aim of the present study is the determination of the effective elastic properties of cellular materials using two‐dimensional cellular structures which are common as core materials for structural sandwich panels as a model material. The cellular microstructure is homogenized by a strain‐energy based RVE‐procedure assuming that strain states, which are equivalent on the macroscopic level, lead to equal strain energy in a representative volume element whether the real microstructure or the quasi‐homogeneous “effective” medium is considered.
