Homogenization¶of Non-Uniformly Bounded Operators:¶Critical Barrier for Nonlocal Effects

Abstract

This paper deals with the homogenization of a class of highly oscillating monotonic operators which are uniformly elliptic but non-uniformly bounded. We determine an asymptotic barrier below which we obtain a classical behaviour and above which nonlocal effects appear. We also prove that this condition is optimal in the case of a fibre-reinforced medium.
