Homogenization of elasticity problems on singular structures
В. В. Жиков · Izvestiya Mathematics · 2002
We consider homogenization theory on periodic networks, junctions and more general singular objects. We show that the homogenized problem typically has a character. This fact is a distinctive feature of homogenization of elasticity problems in contrast to scalar problems. We investigate the properties of Sobolev spaces for various singular structures, prove a non-classical homogenization principle for singular periodic structures of general type and describe a scaling effect for model problems with two small geometrical parameters.
