A local-effective relation in planar linear elasticity
Dag Lukkassen, Annette Meidell, Klas Pettersson
We give an example of a relation between local and effective properties for elastic structures, up to geometric constants. The model considered is a periodic structure with isotrop…

An elementary proof of the Vigdergauz equations for a class of square symmetric structures
Dag Lukkassen, Annette Meidell, Klas Pettersson
For a periodically perforated structure, for which homogenization takes place in the linear theory of elasticity, the components of the effective elasticity tensor depend in genera…
