Unfolding Operator Method for Thin Domains with a Locally Periodic Highly Oscillatory Boundary

Arrietay, J.M.Villanueva Pesquera, M.2023-06-182023-06-1820160036141010.1137/15M101600Xhttps://hdl.handle.net/20.500.14352/24636We analyze the behavior of solutions of the Poisson equation with homogeneous Neumann boundary conditions in a two-dimensional thin domain which presents locally periodic oscillations at the boundary. The oscillations are such that both the amplitude and period of the oscillations may vary in space. We obtain the homogenized limit problem and a corrector result by extending the unfolding operator method to the case of locally periodic media.engUnfolding Operator Method for Thin Domains with a Locally Periodic Highly Oscillatory Boundaryjournal articlehttp://epubs.siam.org/doi/pdf/10.1137/15M101600Xopen access51HomogenizationLocally periodicOscillatory boundaryThin domainUnfolding methodVarying period.Matemáticas (Matemáticas)12 Matemáticas
