Asymptotic analysis for domains separated by a thin layer made of periodic vertical beams

Abstract : We consider a thin heterogeneous layer consisting of thin beams (of radius r) and study the limit behaviour of this problem as the period ε, the thickness δ and the radius r of the beams tend to zero. The decomposition of the displacement field into beams developed in [10] is used, which allows to obtain a priori estimates. Two types of unfolding operators are introduced to deal with different parts of the decomposition. In conclusion, we obtain the limit problem together with transmission conditions across the interface.
