Thin inclusions in linear elasticity: A variational approach. (English) Zbl 0633.73021
The inclusion of a very thin layer of very rigid material into a given elastic body is considered from a variational point of view: as both thinness and rigidity increase, the approximating energies converge to the energy of a limit problem, which depends on the different speeds of thinness and rigidity. In particular, the classical equations for membranes, plates and shells are shown to derive from the system of three-dimensional linear elasticity.
