Abstract
The effective conductivity of composite materials with random position n 2,n ∈ N, and the cylindrical identical inclusions inside periodic cells is considered. We compare the results for symmetric and nonsymmetric cases of location of the inclusions in the cells and find that a symmetric structure provides a minimum for the effective conductivity among all the structures having n 2 inclusions of such conductivity and sizes.
